Does anyone know the dimension of the outer and inner diameter of the bezel insert? I am looking for additional bezel inserts but I don’t know the dimensions 
I just measured mine, inner diameter is 31.7mm, and outer diameter is 39.4mm. Hope this helps
Oh and btw if you manage to find additional bezel inserts that fits besides their own (I mean these here: https://shop.diywatch.club/collections/bezel-bezel-insert), please let me know as well, I am interested in getting one myself as well, thanks!
