Actual correspondence. Actual photos. We can do this for any watch!
"Hello, I am contacting your company to see if you replace watch casebacks. I have a Ball Engineer ll moonphase with a solid caseback and would like to replace it with a sapphire caseback so I can see the movement. The movement is a modified eta 2824 -2 and the case is 41mm. I contacted the company and they do not make a clear caseback for this model. Is this something you could make?
threading was a complicated issue
It is 100% water resistant being a screw on see through back
"That looks terrific. Thank you"
