Apple Watch - SE 3 Repair

The Apple Watch SE 3, or "SE 3rd Generation", or "SE 2025" is, of course, Apple’s 3rd generation of Apple Watch SE.

Keeping the theme of “heavy on features, light on price” marketing, the third-generation Apple Watch SE became available in September of 2025, featuring the same design, display, and chip as the Apple Watch Series 11. This is the first generation of Apple Watch SE that got an always-on display and the same processor as the flagship model, though, unlike Series 11, its screen refresh rate is limited in this mode.

The aluminum-only Apple Watch SE 3 starts at $249 and comes in either Midnight or Starlight. Like other Apple Watches, both GPS-only and GPS + Cellular models are available. Besides labelling, the watch body of the Apple Watch SE 3 looks just like the previous generation of Apple Watch SE.
