Smartwatch Sizing Guide

Like many other people, I didn't know which size of smartwatch would fit me, so I made some accurate 3D printed models of the Galaxy Watch 7 series for myself, but while I was at it I also made Galaxy Watch 8 series + Galaxy Watch Ultra and the newest Apple Watch Series 11 and Apple Watch Ultra 3. 

They all have a 5mm hole so you can thread a cord through and see a bit better how it fits on the wrist. They are fairly dimensionally accurate based on the online info and product photos I could find, but not 100% (eg a 44mm wide can be 43.93mm) so don't use these models for 3D projects that need perfectly accurate dimensions.
