Background and Identification
All Apple Watch Series 3 models can be readily identified by the distinctive red dot on the Digital Crown. As with previous models, the watch comes in both 38 mm and 42 mm configurations in a variety of colors and materials. Internally, the watch features a newly-touted barometric altimeter and a battery with slightly upgraded capacity. Tools and repair procedures remain very similar to Apple Watch Series 2.
The most often replaced Apple Watch Series 3 parts include the battery and screen.
