Major thanks to the original creators of the Apple Watch and Apple Watch band stls on Thingiverse! I've shrunken them and carved a bit out of the back of the watch to fit my Smart Doll.

The watch is approximately 5cm (2 inches) long when assembled.

I printed it with a 0.2 nozzle at 0.06 layer height with supports and rafts.

The screen is printed on my 2d printer on normal paper, cut out and glued to the watch face. The image I used was 50 pixels wide.
