Apple Watch Series 12 Review: Finally, a Readiness Score (2026)
On the surface, the Apple Watch Series 12 doesn’t appear to be a major upgrade over last year’s release and, in many ways, it isn’t. But after a week of wearing it day and night, I noticed that the Series 12 feels more intuitive, putting fewer steps between me and the information I need from my everyday smartwatch.
Health tracking is more thorough, thanks to a new Health Sensing System and faster S11 chip. The watchOS 27 update, first announced at WWDC in June and finally available to consumers, gives the Apple Watch a cleaner, streamlined interface that positions Siri AI at the center of the user experience. The most notable addition is perhaps Audio Intelligence, a suite of listening tools powered by Apple Intelligence. Plus, in a fun return, the Series 12 also comes in ceramic, a premium finish Apple discontinued in 2020.
Not everyone needs the upgrade, though. If you’re coming from the Series 8 or older, the Series 12 is a generational leap, with a better display, longer battery life, and newer health features, including sleep apnea and hypertension notifications. Owners of the Series 9 or 10 have fewer reasons to swap, but the battery improvements alone (18 hours to 24 hours) may be compelling. If you already have the Series 11, Audio Intelligence probably isn’t going to be enough to justify replacing a watch that’s already capable of most of the same functions.
Visually, Apple isn’t fixing what isn’t broken, and I’m not mad about it. The Series 12 looks nearly identical to its predecessors, but Apple highlights it as its thinnest Apple Watch yet. The aluminum and titanium models measure 9.7 millimeters thick, and the ceramic option is 9.85 millimeters thick. I didn’t notice a difference during everyday wear, but the Apple Watch Series remains one of the most comfortable smartwatches I’ve tested. Aside from the new Hermès collection, there aren’t any new band designs this year, but Apple has added new colors to the existing lineup.
The new finishes are exciting, particularly the return of ceramic. Apple first offered a ceramic option with the Series 2 in 2016, and it was discontinued in 2020. Today, it’s available in pearl white and night blue, both of which give the Series 12 a softer finish that looks more like an accessory. The ceramic feels more like a fashionable move rather than a functional one, but Apple is following a trend seen across brands like Oura.
I’m testing the aluminum model in the new dark bronze finish, which has become my favorite. It complements most of my wardrobe and gives the watch a more cosmopolitan look than some of Apple’s sportier colorways. Aluminum models are also available in the standard light gold, black, and space gray; titanium comes in natural and a new radiant gold. The aluminum models are now coated with Ceramic Shield 2, which Apple says is 60 percent tougher than the previous Ion-X glass. I haven’t had enough time with the watch to meaningfully test that durability claim, but for someone who tends to knock their smartwatch on doors and countertops, it’s an improvement I’ll happily accept.
Battery life remains rated at 24 hours, which is slightly disappointing when competitors can go longer between charges. The saving grace is faster charging. Fifteen minutes of charging now provides up to 12 hours of battery life, and five minutes gets you up to 10 hours of sleep tracking. This has been the most useful upgrade for me. I can set the watch to charge while I’m getting ready for bed and put it back on for sleep tracking.
The Series 12 ships with watchOS 27, but most of the software changes will also arrive on compatible older Apple Watches. I particularly love the revamped app layout. Instead of having to hunt through a sea of icons or scroll through an exhaustive list, Apple now surfaces five Siri AI-suggested apps, the Siri app, and a shortcut to the full app grid. The apps I need most are immediately available without cluttering the display.
