Here is my very stylish Sun watch :) I've seen Sun clocks/dials but i never seen wearable version so here it is :)
Technically it should actually work (it's designed for UK latitude) but obviously it will be very difficult to get actual time (it would have to be horizontal and pointing north). Nonetheless it looks cool and it's more decoration value or just for fun :)
For strap I used velcro.
There are two versions, one is good for SLA/DLP and I second version is adapted for FDM printers (recommend to print with 0.06 mm layer resolution)
