Apple Watch Series 12 (GPS)
Apple’s main smartwatch, in 42 mm and 46 mm
If you can stretch the budget, the Series 12 is the one to get: the longest battery life of any regular Apple Watch (up to 24 hours), the most health features, including hypertension notifications and Sleep Score, and a tougher display. If you mainly want notifications, fitness tracking and safety features at a lower price, the SE 3 covers the essentials very well.
- Calls, texts, timers and reminders on your wrist
- Up to 24-hour battery on Series 12
- Health: heart rate, sleep tracking, fall and crash detection
- SE 3 now has an always-on display and fast charging
- Needs an iPhone (not for Android users)
- Series 12 costs noticeably more than SE 3
- Charging every day or so
Best for: iPhone users who want fewer phone checks and better health tracking.
Skip it if: You use an Android phone (look at Samsung Galaxy Watch).
The Problem It Solves
Hands busy cooking, carrying groceries or holding a child, and the phone keeps buzzing somewhere in the house. An Apple Watch lets you see who is calling, reply to messages, set kitchen timers, pay, and check your heart rate without picking up the phone.
