I have SINN U1 on rubber strap, I want to change it to Leather strap. Not sure if every strap out there will fit to it?
I know 20mm does ( is it correct?) .. Below are the two options, Can you suggest which is good? Also anymore options if you have. Need in Black leather and red threading please.
Carbon Fiber Watch Strap - Carbon Fiber Watch Band 22mm Black, Red Stitching
Grand Duke Leather Strap - GRAND DUKE - Leather Watch Strap in BLACK / RED
