UPO case back - desperately looking for

Recommended Posts

Hi there,

first I want to point out, that I did a lot of homework, asked dealers and placed an ad in the WTB corner but unfortunately no success yet.

I am in need for an UPO case back for the 45,5mm model. Mine is from an early batch with swiss ETA 2824-2 and came with a bad case back (I posted that years ago here and over on RWI or RG, don't remember). My case back is bad because there is no noticable waffle pattern around the seamonster and it is more matte than polished :( .

Some members offered case backs to me as well as some dealers but the threads didn't match my case although all of them are called UPO. There must be a huge number of makers and it seems that the case/ case backs are different just by a mm.

So please allow to call for a case back here in this section.

BTW: I don't want to swap the whole case because a gen tube and crown is installed and it has got chief's ar.

I am needing one with a thread diamter of exactly 35,77 mm as you can see from the pic below. I am looking for en excellent waffle texture well polished. Any offer is much appreciated :thumbsupsmileyanim:
