In anticipation of the upcoming media event, decided to make some Watch frames for making up designs. Includes both 38mm and 42mm sizes, which also use the official screen dimensions (according to Watchkit's documentation).
There's two styles to choose from: lined or detailed. Both are meant to be very basic and subtle, so that the focus stays on the app's design. Which... That and the accurate screen dimensions were the main motive for doing this.
I also had some fun recreating Apple's official apps, as seen in the official pictures. You can see them in the attached preview of the Sketch file's contents.
Hope it helps :)
