I found nice looking pocket size sundial compass from one antique & handcrafts event where i was selling my products about six months ago. That nautical style is very close to steampunk aesthetics so i wanted to use it for making new prop for my "neo-Victorian gentleman's" costume and this is the final result.
There is one online shop who sell similar brass sundials if you also want to make own "antique solar wristwatches". [link]
Lol.. I just noticed, that also Museum Replicas have started to sell very similar wristwatches like this. [link]
