The Apple Watch First Generation is often referred to as Series 0 and uses a single-core S1 system on chip.

It is equipped with a built-in heart sensor that uses infrared and visible-light LEDs. All versions of the first-generation Apple Watch have 8 GB of storage and an operating system that lets the user store up to 2 GB of music and 75 MB of photos.
