Hi guys,

I'm looking for a bit of help, I've got a seamster 200 from 1991 that needs new gaskets.

I've done a bit of digging and it seems there are just some generic gaskets I could use, but wondered if anyone had any experience replacing the gaskets or knew which specific part numbers I should be looking for?

Thanks in advance!

 

The watch in question

 

Quartz version, correct? If so...

Crystal gasket - 098EG2124

Case back gasket - 088NS0824

Crown doesn't call out a replacement O-ring (not uncommon) so implies the entire crown would be replaced - 069ST42113M.

Cheers, Al

 

It is a quartz,

thanks so much for your help Al!

 

Just for future reference, is there anywhere that’s a good source for this sort of info? Or does it just come with experience? I noticed you’re an Omega watchmaker

 

I have access to the Omega Extranet, soi can look this information up. The information isn’t public.

Cheers, Al

 

Ah I see!

thanks again Al, really appreciate it!

 

Hi Al,

I wonder if you wouldn't mind looking up the correct crown seals for a 166.077 Seamaster 200?

Cheers!

 

That's a Ploprof case number - is that what you are after?

 

Sorry, yeah been working on a 600 recently.. I meant 166.091 case.

 

Make a new thread Scott.

 

Not really a "pre-bond" in the sense most people think, but the new crown for it is 069ST42062. No crown seals are listed.
