Why Choose This Product

The Apple Watch SE 3 GPS + Cellular 44mm is designed for users who want core Apple Watch health, fitness, safety and connectivity features without moving to the higher-priced flagship Watch models.

The cellular configuration is especially useful if you exercise, commute or leave your iPhone behind regularly. With a compatible mobile plan, supported communication and streaming features can continue directly from your wrist, while the built-in GPS independently records routes and workout metrics.

The 44mm model also provides a larger 368 × 448 display than the 40mm version while still weighing only 33g in GPS + Cellular form. Its Always-On screen, 1,000-nit brightness and S10 processor make it significantly more capable than earlier SE generations.

For everyday wellness, SE 3 adds useful features including temperature sensing, Sleep Score, sleep apnoea notifications, heart-rate monitoring and Vitals, while safety tools such as Fall Detection, Crash Detection and Emergency SOS provide additional reassurance.
