The Apple Watch Series 1 models were similar to the original Apple Watch (also known as “Series 0”), but used a more powerful dual core processor. Like its predecessor, this Apple Watch was controlled with a Digital Crown and a Force Touch display, and it needed to be paired with iPhone 5 (or newer).
This Apple Watch Series 1 model is a 38mm version (a 42mm version was also available) and used a 272 × 340 display.
The Apple Watch Series 1 was originally sold in four standard configurations:
silver aluminum case with white Sport Band
gold aluminum case with cocoa (dark brown) Sport Band
rose gold aluminum case with midnight blue Sport Band
space gray aluminum case with black Sport Band
The Sport Bands were made of fluoroelastomer rubber. This Apple Watch Series 1 version has a silver aluminum case with white Sport Band.
