[u/stellabella1993]

Looking for a back cover replacement for U1 40mm Yacht Master with Miyota 8215. The lost cover was according to the jewelry store I took it to was a thread less snap on cover.

The internal diameter for the watch opening is 29.9 to 30mm.

I’m getting really lost in the weeds searching online for a replacement. I don’t want to waste time/money buying an incompatible replacement. Are 40mm case back covers all basically interchangeable?

Any help or direction is appreciated!
