So I got a smartwatch and put on a metal strap. As the watch has a heart rate sensor on the bottom, I feared the metal strap would scratch it if I took it off but didn't put it on a charging stand. My solution was the "Watch Board".
Once I put it on I found it was much more comfortable to mess with my watch for setting it up etc as well.
If others find this useful I will upload more sizes. The 4 I have now are just slightly different (a few mm.)
