I have created an Apple Watch UI Kit. It is a flat UI Kit that has most of the elements that you would find in the soon to be Apple Watch. The UI Kit is currently in red, however you can change this to any colour you wish.
I have created the file in Illustrator, however if you would like me to upload a version in Photoshop, then please comment below.
Whats included in the Apple Watch UI Kit?
In this kit, you can find 4 watch views, one with a plain strap, one with a custom strap, a side view and an angled view. There are also a large selection of elements and dotted and dashed boxes with multiple arrow heads as well.
I have included this wireframe example to the Illustrator file on a separate artboard.
You can find the Apple Watch here.
