Finest Prices Today: Apple Watch Series 12 (42mm)

Revealed along with brand-new iPhones and AirPods at Apple’s Surprise and Shine press occasion in early September, the Apple Watch Series 12 is the current and would want to be the best entry in the business’s long line of smartwatches.

In 2015’s outstanding Series 11 currently controlled the premium smartwatch market with ease. To that gadget’s list of qualities, the Series 12 includes updated health sensing units, a brand-new app, engaging AI-powered audio functions, a more effective processor, enhanced fast-charge abilities, and some charming brand-new products and color surfaces. It even handles, versus all chances, to keep the very same beginning cost as its predecessor in the middle of a gush of cost boosts somewhere else.

With Apple declining to upgrade the magnificent Apple Watch SE, the field appears clear for the Series 12 to slot in as the very best Apple Watch, and for that reason as the very best smartwatch on the marketplace. Life is seldom that basic. I invested 2 weeks with the Apple Watch Series 12, screening and assessing its style, functions, battery efficiency, and more, all so we can bring you extensive, professional purchasing guidance. Is this the smartwatch for you? Continue reading to learn.

(For wider guidance, inspect our guide to the very best Apple Watch in 2026.)

As I’ve explained in a different short article, the Apple Watch style didn’t alter in any essential methods this year. It’s the exact same shape, the very same measurements, the exact same buttons. Which isn’t always a bad thing, since Apple’s style is a modern-day classic: a smooth and slimline chassis which feels inconspicuous on the wrist and is user-friendly to utilize. The principles were constructed to last.

There’s one non-visible modification, which is that the aluminum designs get a screen upgrade from Ion-X glass to Ceramic Shield 2 that Apple states is 60 percent harder.( The more costly designs stay on Sapphire crystal, a much more scratch-resistant product, however one which is more susceptible to drop effects– not that drops need to be much of a problem for a smartwatch. )That’s not a simple claim to test, and I can’t state I saw a distinction from the previous generation, however it’s a good benefit in regards to assurance.

And after that there are the strictly cosmetic distinctions. These are definitely worth pointing out, partially since the Apple Watch is to some degree a style device, and partially since they’re so fantastic.

The returning ceramic product, for instance, looks wonderful in both Pearly White and Night Blue. You’ll need to pay a premium for that alternative, which begins at $ 899/ ₤ 849, so a much better bet might be to stick to the most inexpensive aluminum case product, however select the brand-new and spectacular Dark Bronze surface. Macworld’s evaluation system is a really wise black system, however I’ve experienced major Bronze envy. If you choose the titanium case, think about the brand-new Radiant Gold surface, which has a stunning shine to it. There are great deals of chances, simply put, to get a gorgeous surface and concurrently flaunt that you’ve got the most recent design. Possibly the long-awaited style will lastly get here next year (or perhaps it’ll be postponed yet once again), however in the meantime these surface-level modifications are enjoyable and fresh.

Apple

I will raise one quibble worrying the construct quality of this generation: the assembly of my Series 12 evaluation sample does not appear rather as perfect as I’ve concerned anticipate from this line of product. When I run a finger throughout the face and on to the surrounding bezel, I can feel a sharp edge where one product paves the way to another. For contrast, I instantly inspected my 2 older Apple Watches and discovered that the SE 3 had a minor edge, however it was less obvious than the Series 12, while the Series 11 had practically no noticeable edge at all.

I do not understand if this is substantial– the outcome of expense cutting, a modification in producing tolerances, or some other systemic element– or if I simply got unfortunate and got a somewhat malfunctioning system. (If it’s the latter, my associate Mahmoud Itani likewise got unfortunate. He reports the very same problem.) I would likewise like to tension that this is an extremely small quibble that does not especially trouble me: When I state sharp, I suggest just that it’s difficult and unexpected, not that there’s any threat of cutting yourself on it. It’s really uncommon to come throughout flaws like

this when examining an Apple item, and not completely assuring as a prophecy of things to come.

Apple Watch Series 12 efficiency

It isn’t usually needed to dig unfathomable into the tech specifications when evaluating a smartwatch. The Series 12 has 64GB of storage, for instance, however that’s not likely to have much of a result on your daily experience. Its screen has the very same variety of pixels as on the previous 2 generations, and the pixel density hasn’t altered considering that the Series 4; Apple long earlier reached a level of sharpness that was appropriate for the task and hasn’t troubled altering it given that. And while the RAM allotment is unofficially comprehended to have actually doubled from 2GB to 4GB this year, you would not understand it from Apple’s released specification sheet or basic efficiency.

One product on the specification sheet that does appear substantial, nevertheless, is the brand-new S11 processor. Not since the Apple Watch required more processing power when dealing with apps; unless you own something truly old, it’s not likely you’re encountering significant traffic jams in this location. Since of the brand-new things it permits the Series 12 to do.

Undoubtedly, AI is a huge part of this formula. While older watches going back to the Series 9 are retrospectively suitable with Siri AI, the Series 12 is the very best geared up to manage its needs. And just the Series 12 gets access to the brand-new suite of AI-powered Audio Intelligence functions, which I’ll talk about in the next area. These, Apple states, are completely depending on the S11 chip and particularly its Secure Enclave.

The S11 chip’s power and elegance need to likewise assist with battery efficiency, something that might show crucial provided the addition of constant heart-rate tracking and the power needs of this function. (Battery life too will be talked about later on in this evaluation.) And Apple states the precision of the health sensing units themselves is indebted to the abilities of the S11.

If you’re trying to find a basic speed increase, nevertheless, my experience recommends this isn’t the expect you. I can’t keep in mind ever discovering my Series 11 or my SE 3 slow (both have the S10 chip), so it’s difficult to see that there was much space for enhancement. Even worse, from time to time I got the impression that the Series 12 is slower than those designs. It’s tough to be clinical without a benchmarking app, however here are a couple of subjective examples that provided me a tension about the Series 12’s speed and responsiveness:

• Shazam on the watch (triggered by hand) when “believed” for so long that the tune ended without any details provided.
• On one event, I strolled for a complete hour and the watch never ever acknowledged I was active or recommended an exercise.
• I entered into Activity to examine my actions, and it was still revealing an old count from an hour formerly. It took 10 to 15 seconds to upgrade this, while I enjoyed impatiently.
• On another celebration, the watch didn’t provide me a sleep rating till 10.25 am, long after I got up (and after I ‘d done a complete exercise, ridiculously).
• The majority of irritatingly, 3 times on a single day, my Series 12 spontaneously reset without being asked.

David Price/ Foundry

There might be descriptions for some or all of these inconveniences. Maybe Shazam suffered from a bad web connection rather than an absence of processing muscle (although my iPhone was doing fine at the time), and maybe I stopped working to set off a recommended exercise since I was strolling slower than typical. It’s likewise been reported that the watchOS 27.0.1 upgrade has actually resolved the restarting concern.

Still, I’ve been utilizing one Apple Watch or another almost every day for well over a years now, and I can inform you with self-confidence that I’ve grown to anticipate much better. Whether it’s down to problems with existing models of watchOS, or processing resources being diverted to brand-new functions, my Series 12 merely provides me the subjective ambiance of being a little less responsive, a little less trustworthy, than other Apple Watches I’ve utilized in the current past. Which isn’t what you desire, or anticipate, from a gadget with an effective brand-new chip.

Apple Watch Series 12 functions

With style mainly remaining the exact same and tech specifications having little influence on the user experience, the concern of encouraging clients to update falls greatly on the function set. On the favorable side, this broadens in a number of appealing methods this year. The only issue is that rather a few of the brand-new functions aren’t really prepared.

Take Audio Intelligence, the suite of functions loosely organized under the styles of AI and noise. There are 4 of these: Sound Recognition, Music Recognition, Live Rewind, and Siri Recap. The latter 2, which by the way are without a doubt the most intriguing of the set, aren’t presently offered, and Apple hasn’t even called a date for their launch. The assistance file states just that they “will be offered in beta later on this year, beginning with English.”

The morality of this sort of thing is arguable, to state the least. Unsurprisingly, considering that they’re so futuristic and feel so helpful (even if there are personal privacy and basic AI ickiness issues to be browsed), Live Rewind and Siri Recap were both popular in the launch discussion. On some level Apple was hoping to persuade individuals to purchase the brand-new gadgets on the strength of these functions, without being prepared to state when the functions will get here. We’ve been here before, and Apple has the legal costs to reveal for it; ideally its experience because case will guarantee fairly timely shipment in this one.

David Price/ Foundry

Back to the functions themselves. Here are my ideas:

Sound Recognition

As long earlier as iOS 14, the iPhone had the ability to determine particular noises– doorbells, smoke detector, sobbing infants– and after that inform you if it heard them. It’s a function with massive, even life-saving capacity for those who are deaf or difficult of hearing. This year the function concerns the Apple Watch, so it will not matter if you unintentionally leave your phone upstairs.

It’s easy, helpful, and appears reputable: in each of my tests there was a quick hold-up of possibly 3 seconds after the noise, and after that a notice appeared.

I evaluated for doorbell, door knock, feline, pet, running water, breaking glass, automobile horn, and sobbing infant. The function discovered all of these with practically 100 percent precision when it heard them. Smoke detector and emergency alarm were at first less trusted when I evaluated them utilizing YouTube videos, which may appear extremely bad … up until it struck me that an incredibly high volume was most likely part of the algorithm. When I utilized the screening button on a real smoke detector, it got a lot more precise. After these tests, I’m delighted to state that Sound Recognition can dependably find all the noises it states it can.

On the other hand there were incorrect positives, and rather a lot of them. Throughout screening, the watch has actually wrongly recognized (non-doorbell) sound impacts in numerous television programs and YouTube videos as a doorbell, or heard me tapping a spoon on a pan to leave the last of the pasta sauce, for instance, and translated this as a door knock. It remarkably often believes there’s a pet dog neighboring (however really seldom a feline, for some factor) and has more than when alarmed me by declaring to hear damaged glass when I’m just putting away dishware.

It’s a creative and rather excellent function in numerous methods, however anticipate some incorrect alarms and undesirable notices. I highly recommend users to just switch on the particular noises they definitely require to be able to find.

Keep in mind that the function is off by default; you require to enter into Settings on your iPhone, go to Availability> Noise & & Name Recognition> Sound Recognitionswitch on Sound Recognitionand lastly switch on Identify utilizing Apple Watch

Music Recognition

This successfully modifications Shazam from an actively activated to a passive background function. The watch is continuously listening out for music and will emerge the details in the Smart Stack when it identifies it.( To turn this on, enter into Settings on the watch, choose Smart Stackand after that switch on Music Detection)

Provided my concerns with Shazam being sluggish when by hand set off( see the previous area), and the danger of lacking tune before it reaches a conclusion, this comes in handy. It isn’t rather rapid: when I raise Smart Stack, it usually takes a number of seconds for the Shazam widget to appear, or to revitalize from the last tune it identified. It’s much quicker and more trustworthy than when utilizing that app by hand, thanks to the info it collects before you ask. Thumbs up.

Live Rewind

Now we get into the truly intriguing functions … and likewise, unfortunately, the ones which aren’t readily available. The staying Audio Intelligence includes continue the style of background listening, however include the faintly scary twist that they’re monitoring your discussions.

Live Rewind is the easier of the 2. At any time( as soon as it introduces), you can double-press the Digital Crown, and it will show a records of the last 15 seconds. Really helpful, most likely, if you have a hard time to keep in mind all the specials and do not wish to ask the server to duplicate themselves. Less efficient if you’re attempting to keep in mind the start of a prolonged joke or anecdote.

Apple knows the personal privacy ramifications, and there are lots of safeguards. The restricted length of the transcription is one. Another is the effort to make certain individuals close by understand what you’re doing: this is accomplished by means of a trigger noise that can’t be silenced, an on-screen animation, which ideally recognisable double-press action. It likewise isn’t continually taping. Just bits that are contacted and after that specifically conserved to the Siri app will be kept.

I truly like the noise of this function (especially the relative absence of “AI-ness”), however I want Apple would have postponed the statement up until it was really prepared.

Apple

Siri Recap

This one’s a little bit more involved and a little bit more reliant on AI. Siri Recap eavesdrops the background and makes notes on your discussions, which it will later on sum up. The concept seems that you set up or geofence the function so it’s just listening when you’re at work, for instance, or you can simply turn it on and off by hand. Or, I expect, have it on all the time, however get ready for your good friends and enjoyed ones to be frustrated when they discover.

Keeping in mind the dreadful alert summaries we sometimes saw in the early days of Apple Intelligence, I will delay my ideas on this up until I can check its dependability.

New health sensing units

Far From Audio Intelligence, the Series 12’s staying heading brand-new functions go back to the familiar worlds of fitness. Most especially, we have a completely brand-new” health picking up system “with a 2nd-gen electrical heart sensing unit.

Apple states the brand-new sensing unit guarantees much better contact with the skin, and functions revamped photodiodes and bigger, power-efficient green LEDs. It ought to for that reason take more precise readings. It likewise takes, well, more readings. Whereas previous Apple Watch designs determined the user’s heart rate as needed, throughout exercises, and every couple of minutes at other times, the Series 12 simply does it continuously. Every 5 seconds, all day, to what ought to be a high degree of precision.

David Price/ Foundry

This might not look like a huge offer, due to the fact that you might feel that at any time you need to know your heart rate, you can ask for it. First of all, this is a much more practical method of accessing that details: there’s a brand-new watch face issue for heart rate, so now you simply require to glimpse down, and the number is right there. And more notably, having access to heart-rate information all the time makes it possible for the Series 12 to reach more educated conclusions about the state of your health, your physical fitness, and even your tension levels.

The brand-new sensing unit system likewise includes a higher focus on HRV (or heart rate irregularitya metric which physicians discover helpful in evaluating heart health and physical healing, and in detecting issues with sleep, tension, diet plan, and more. HRV was determined formerly, however on the Series 12 is determined 24 times as frequently and is shown in a brand-new area of the Heart Rate app. Once again, this is more most likely to be beneficial in the method it feeds into more comprehensive insights appeared in the Health app than in servicing the user’s unexpected interest to understand the number.

Preparedness

The last brand-new function I wish to discuss is the Readiness app. This is developed to boil down a wide range of health, sleep, HRV, and other metrics down into a single, quickly understandable rating out of 10 that shows how prepared your body is for a workout session.

When I open the app now, for example, it offers the decision “9: Go For It.” When I scroll down, it broadens on this to discuss that my high sleep rating from last night and my typically lower activity levels in current days indicate today is a fantastic day to press hard.

David Price/ Foundry

As ever, I like simpleness. The Apple Watch Series 12 has access to a massive amount of health information, however to the non-scientific layperson like myself, the majority of it is quite near to incomprehensible. Boiling it down in this method makes it beneficial. There’s something I can do with that rating.

And while this will doubtless differ from individual to individual, I can state that physical preparedness for workout is something I fret about a lot. As a physical fitness lover in early midlife with a significantly vulnerable body, I wish to press the limitations, however I do not wish to surpass them and wind up with an injury or disease. Having the thumbs-up from Readiness will offer me a good deal more self-confidence in the health club.

Keep in mind that Readiness requires an unexpected quantity of time to prepare yourself: you require to use it to bed for a minimum of 7 nights before it’s prepared to begin providing those decisions. That’s relatively basic for such gadgets, and a Whoop or Fitbit will make comparable needs for comparable functions. I discovered it slightly irritating that up to this point the app firmly insisted on its primary screen that there was” No Data,” even though scrolling down showed that there was a terrific offer … simply not yet adequate. It may look like a little quibble, however this

appears a counterproductive and even deceptive method to manage setup.

David Price/ Foundry

The Readiness app, I’m pleased to state, is readily available now. Larger combination of its findings will have to wait till the iOS 27.2 upgrade, when the iPhone will get an upgraded variation of the Health app. That will( amongst a great deal of other brand-new functions) consist of a Readiness tab and the capability to take a look at Readiness information on your phone. iOS 27.2 must be here quickly, and might even have actually gotten here when you read this evaluation; you can learn more about the upgrade here.

Apple Watch Series 12 battery

Formally the heading battery life hasn’t altered because in 2015: the quote, as on the Series 11, stays “approximately 24 hours.”( That, by the way, was a huge and unexpected dive from the 18 hours which had actually been declared for all 10 previous Series designs.) Our tests, nevertheless, show that this considerably ignores what you can anticipate in normal day-to-day use. Whether durability has actually enhanced or deteriorated from the previous generation is more difficult to state, because efficiency was extremely irregular.

The Series 11 was great and consistent. In each test, it lasted 2 days and 2 nights before ending early on the early morning of the 3rd day: it handled 46 and 49 hours respectively for approximately 47.5 hoursIn my evaluation, I explained that efficiency as exceptional, and I wait that evaluation.

The Series 12 did even much better on its very first run, making it to 10 am on the 3rd day, for an overall of 51 hours. I was rather blown away by this, specifically remembering the brand-new addition of consistent background heart-rate tracking, which one may anticipate to have an influence on battery efficiency.

Then I ran a 2nd test, and the Series 12 hardly made it to bedtime on the 2nd day, passing away quickly after 11 pm: that’s a relatively weak 40 hours, and provides a typical throughout the 2 runs of 45.5 hoursResulting in the conclusion that a) the Series 12 has somewhat weaker battery efficiency than its predecessor typically and b) it’s likewise far, far less constant in this department.

A degree of disparity is to be anticipated, since smartwatch battery tests are not a specific science; there’s no recognized standard we can utilize to straight compare gadgets. The accurate time your Series 12 lasts will depend upon what you make with it. (And it will undoubtedly deteriorate with time.) The lit-up screen is clearly more of a power draw than the dimmed always-on variation, and any active app use will drain pipes the battery quicker than having it run passively.

In the past, Workout has actually usually been among the larger battery sappers. It does not appear specifically uneasy nowadays: a 30-minute operate on the treadmill with the buddy iPhone neighboring led to the Series 12 dropping from 99 percent to 97 percent, which isn’t regrettable. I will keep in mind that the 2nd test, the one which fell so disastrously brief of our expectations (while exceeding Apple’s, to be reasonable), consisted of 2 longish strolls with Workout in operation. That might have been an aspect, although it might barely be to blame for such a big variation.

While we’re on the subject, by the way, Apple declares it has actually included some battery enhancements particular to work out sessions. Based upon tests without an iPhone close by, the business approximates that the Series 12 will last for 10 hours of outside exercises, which is a declared 25 percent boost on the previous generation. If you prepare to do a great deal of ultramarathons, you might be much better off with the brand-new Apple Watch Ultra 4, which the business states benefits 18 hours of outside exercises, 25 hours with the brand-new Extended Workout mode, and approximately 45 hours with Max Extended Workout mode. (These modes are not offered on the Series 12.)

Fast-charging

As soon as the battery is drained pipes, you’ll have the ability to top it up rapidly … however possibly not rather as rapidly as Apple believes. The business states you can obtain from 0 to 80 percent with 30 minutes of fast-charging, however our tests recommend this is rather positive. Once again, efficiency was frustratingly irregular.

Utilizing the bundled charging puck and a huge 67W power adapter, my Series 12 made it to simply 58 percent in the designated half hour, and took practically an hour to get to 80 percent. It was totally charged after 82 minutes. I duplicated the test a couple of days later on, and this time it went from 0 to 72 percent in half an hour( and was totally charged after 63 minutes). Those are hugely various outcomes.

I compared notes with an associate from Macweltwho reported yet another outcome: their Series 12 handled 62 percent in half an hour. With 30 minutes of charging (and a suitable and adequately effective battery charger, of course) you can anticipate to improve your Series 12 from 0 to 58 percent, 62 percent, 72 percent, or some other number totally. Do not anticipate to make it to 80 percent, unless you’ve got access to the exact same strange super-chargers as Apple’s research study group.

Those very same Apple scientists declare that, if you’re promoted time, 15 minutes of charging will get you adequate power for 12 hours of regular usage, which is an enhancement on the 8 hours declared for the Series 11. And in a genuine emergency situation, 5 minutes of charging prior to bed ought to suffice for 10 hours of sleep tracking. My suggestions would be to take these claims with a pinch of salt.

Apple Watch Series 12 rate

The Series 12 starts at $399 if you plump for the smaller sized size and can handle without cellular. That’s the exact same cost as the most inexpensive Series 11 design at launch last fall (the Series 11 is no longer readily available), which is an enjoyable surprise: Apple raised the rates of its Macs, iPads, and iPhones this year in action to the worldwide RAM lack, so we were anticipating something comparable for the Apple Watch. Rather, it keeps the exact same entry-level rates.

It’s not all excellent news, as the bigger 46mm variations of the Series 12 are a bit more pricey than their equivalents in 2025. These are mercifully little boosts, compared with the carnage in other places.

• Apple Watch Series 12 (42mm, GPS): From $399/ ₤ 369
• Apple Watch Series 12 (42mm, GPS + cellular): From $499/ ₤ 469
• Apple Watch Series 12 (46mm, GPS): From $449/ ₤ 419
• Apple Watch Series 12 (46mm, GPS + cellular): From $549/ ₤ 519

Here’s the (remarkably comparable) prices since fall 2025:

• Apple Watch Series 11 (42mm, GPS): From $399/ ₤ 369
• Apple Watch Series 11 (42mm, GPS + cellular): From $499/ ₤ 469

Should you purchase the Apple Watch Series 12?

The Series 12 definitely isn’t a bad smartwatch. It looks fantastic and feels comfy on the wrist; the user interface is simple to utilize; it has strong and sometimes remarkable battery life; and the current upgrades indicate it provides the most precise fitness information collection and analysis of any Apple item to date. I like the brand-new Readiness app( a terrific idea, straightforwardly performed), and was extremely happily amazed not to see a large rate walking. There are lots of things to be joyful about.

Compared to the accomplishments of the last generation, the outstanding Series 11 and the impressive SE 3 (what an embarassment we didn’t get an SE 4 this year, by the method), I can’t assist sensation dissatisfied. The Series 12’s battery life and charging speed, while strong in seclusion, are far less constant than those of its predecessors, which indicates you can’t count on a provided level of efficiency when it actually matters. There were uncharacteristic inconveniences: a small flaw in the assembly, minutes of sluggishness, duplicated spontaneous resets. And the majority of irritating of all, the item was released with 2 of its flagship brand-new functions and complete platform-wide combination of a 3rd yet to introduce to the general public.

I seem like the instructor of a smart student who’s had a bad term. Okay. I anticipated much better.
