Apple Watch SE 3 (GPS, 40mm) vs Apple Watch SE 2 (GPS, 40mm)

The SE 3 is the better watch for most people. It adds an always-on display, temperature sensing, sleep apnea alerts, a sleep score, faster charging and the newer S10 chip. The SE 2 still covers the basics: workouts, heart rate alerts, fall and crash detection, and Family Setup. Both use aluminum cases and 50 m water resistance, so build is close. Owners rate both 4.4 out of 5; the SE 3 is the one to step up to unless you want the lowest-cost entry into watchOS.

• Choose the Apple Watch SE 3 if you want an always-on display, temperature-based health insights, sleep apnea notifications and faster charging.
• Choose the Apple Watch SE 2 if you want the core Apple Watch health, safety and fitness features and do not need an always-on screen or temperature sensing.
