I jumped from the Apple Watch Series 7 to the Series 12, and these 7 upgrades made it worth it

My Apple Watch Series 7 did its job for almost five years. It tracked my workouts, helped me set timers, and notified me about messages I should've ignored. Then Apple's watchOS 27 update left it off the supported list, and it had a horrible battery health score that led to it being on the charger more often than I needed it on my wrist, and it was time to upgrade.
