Gen sub w pointy crowns

The profile shape of the CGs makes me think 1665, but it's missing the o-ring groove on the top deck.

It does look like a 4-digit case, where would the crystal press in with the rehaut like it is?  Which leads to the real problem, circled in red.  I don't know if you'll ever get it waterproof.

I have bought a similar case on the bay, polished serial numbs..was supposed to be 16610 - it is not.

3135 wont fit - it will take 1570/3000 only.
I am struggling with the case back as it is larger than a 16610.

Someone knows if the 16800 could take a slightly larger case back than the 16610 - thought they were identical? Thanks for any hint on this..

Hmm

I bought a wm9 sub case and my watchmaker tried 10! and none fit, fortunately he kept bending one to make it fit

I don’t want to do that again and i don’t have any gen movements, i was going to use an ETA
Now I’ve no idea

Any chance it is a 1675 case?
That would be great

"I‘d say it’s no 4 digit case, as they hadn’t a groove for the o ring at the case where the caseback screws on to."

 

I agree.

All 5512/13 and 1680 have case back gaskets mounted in the case back, only the 1665 had the gasket mounted in the case.

"Thread diameter is 30.95mm might be an early 16800 or a 1675."

 

All 1675 have wide CG and are machined for 5.3mm crowns, they will not accept 6.0mm and 7.0mm crowns without modification.

 

Here is a 1675 GMT case:

The info above might eliminate a few models but it still does not tell what your case is for sure...16800 may be a good guess.  I do not know much about 5 digit models at all.

Thanks Automatico - great post. Good infos indeed - so not a 1675 then / it has a gasket on the case. Did not think about the 1665. I was working on a few 16610 and bought this case as it was mentioned 16610.
Now I did buy a few case backs for my 16610s - including gens and some were mentioned 16610 & 16800 so thought they were the same diameter. Would like to find out if 16800 cases evolved from the earlier models to the 16610 cases then.

Did order another case back with 30.95mm thread. Will see.
