Apple unveiled the Watch Series 12 alongside the Watch Ultra 4 last September, bringing a new chipset, upgraded health sensors, and improved battery life to its smartwatch lineup. While it doesn’t stray far from the design of its predecessors, there are a few changes worth looking at.

I’ve been using the 42mm version for a while now, and while Apple’s latest wearable brings a few welcome changes, the overall experience feels rather familiar. There are some improvements worth talking about, particularly when it comes to health tracking and battery life, but whether they make a meaningful difference depends on what you’re looking for in a smartwatch.
