Case condition Sea-Dweller 1665

[Alexander88]

Hello,

I have heard that on the Sea-Dweller 1665 you can judge the condition of the case by the "depth" of the Helium Escape valve. On heavily polished watches, it comes out more and no longer sits properly in the case.
My watchmaker now told me that you could probably adjust the position of the valve.
Is this true? Would then make this criterion for case condition worthless.

Attached is my 1665 I bought last week, what do you think of the case condition? I think it has already lost some material due to polishing. On the other hand, the case is still quite "pointy".
Crown guards don't look optimal to me either.
Would appreciate opinions.

Kind regards

Alex
