Hallo, excuse me if I reopen this thread: I made the same build but with Sternkreuz plexi.
It is a little loose on the rehout (while the retaining ring is very stiff on the plexi) and it rotates when I use the bezel. If I try, all the bezel group and plexi pull off together.
I tried to use hypocement between the plexi and rehout but it just stay in place for 3 or 4 days, then it starts to pull off again if I pull.
Is there any trick I can use to make a very safe build, possibly waterproofed? (for waterprofeed I mean washing hands, a little swim, no submarine activities at all)
Thank you very much!
