It also picks up 5G RedCap connectivity, Ceramic Shield 2 glass on aluminum models that Apple says is 60% tougher than before, a new ceramic case option, and faster charging that delivers 12 hours of use from a 15-minute top-up. Software-exclusive features like Recovery HRV, daytime vitals, a Readiness score, and Audio Intelligence tools such as Live Rewind and Sound Recognition arrive only on the Series 12. Pricing stays flat at $399, the same starting price the Series 10 launched at in 2024, and Apple has already discontinued the older model.\n\nThis is Apple settling into the same slow-drip upgrade cycle it runs for the iPhone: keep the design, swap the internals, and dangle a handful of software features as the real hook. The health-tracking upgrades are the most substantive part of the release, turning the Watch further into a recovery and readiness tool rather than just a step counter, which matters if Apple wants to keep pace with dedicated fitness wearables.\n\nIf your Series 10 still gets you through the day, the case for replacing it is thinner than Apple's marketing suggests; the case for buying new at $399 instead of a discounted Series 10, on the other hand, is not.","[\"apple-watch\",\"wearables\",\"health-tech\",\"hardware\"]","2026-09-22T16:13:36.000Z","2026-09-22T16:58:02.507Z","2026-09-22T16:58:08.463Z","published",null,[],"consumer-tech",[26,27,28,29],"apple-watch","wearables","health-tech","hardware",[31],{"name":32,"url":33},"MacRumors","https:\u002F\u002Fwww.macrumors.com\u002Fguide\u002Fapple-watch-series-10-vs-12\u002F",0,{"sections":36},[37,42,47,52,57,61,66,69,74,79,84,89,94,99],{"name":38,"slug":39,"count":40,"latest_published_at":41},"AI","ai",4195,"2026-09-22T19:28:23.000Z",{"name":43,"slug":44,"count":45,"latest_published_at":46},"Security","security",702,"2026-09-22T21:01:05.000Z",{"name":48,"slug":49,"count":50,"latest_published_at":51},"Policy","policy",366,"2026-09-22T18:04:41.000Z",{"name":53,"slug":54,"count":55,"latest_published_at":56},"Deals","deals",200,"2026-09-22T19:28:55.000Z",{"name":58,"slug":29,"count":59,"latest_published_at":60},"Hardware",167,"2026-09-22T20:00:00.000Z",{"name":62,"slug":63,"count":64,"latest_published_at":65},"Science","science",131,"2026-09-22T16:26:30.000Z",{"name":67,"slug":24,"count":68,"latest_published_at":60},"Consumer Tech",110,{"name":70,"slug":71,"count":72,"latest_published_at":73},"Software","software",79,"2026-09-22T19:44:31.000Z",{"name":75,"slug":76,"count":77,"latest_published_at":78},"Dev Tools","dev-tools",78,"2026-09-18T04:00:00.000Z",{"name":80,"slug":81,"count":82,"latest_published_at":83},"Startups","startups",63,"2026-09-22T21:24:11.000Z",{"name":85,"slug":86,"count":87,"latest_published_at":88},"Gaming","gaming",45,"2026-09-22T15:35:06.000Z",{"name":90,"slug":91,"count":92,"latest_published_at":93},"General","general",43,"2026-09-21T23:48:56.000Z",{"name":95,"slug":96,"count":97,"latest_published_at":98},"Reviews","reviews",27,"2026-09-22T13:00:00.000Z",{"name":100,"slug":101,"count":102,"latest_published_at":103},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
