Hi to all,
I recently picked up Omega Seamaster cal 565, case ref 166.065, gold plated 40 microns case, movement running and needs cleaning... However, some case parts missing, so I'm trying to source them.

To be more precise, missing parts are:
- back gasket
- inner rubber "buffer" 088NS9401, which BTW has ridiculous price at Cousins...
- Finally, it has no proper crystal, so I ordered PC5164 crystal with white chapter ring from ofrei.

When it arrived, everything is fine but I see that crystal is slightly loose in case... When I looked better, it seems it needs sort of gasket/ring for keeping crystal in case?
Or I'm missing something?

Anyone knows part number for that gasket?

Any info appreciated, thanx in advance.

P.S. I didn't post pictures at the moment because watch is not by me, I will do that later during the day if needed.

 

Case back gasket is 088NS5133.

Crystal has tension ring, so no gasket to hold it in place as the ring does that - should be press fit into the case.

 

Thank you. I inspected again the case and crystal. Crystal is really cylindrical shape, that is what confused me. Now it is clear it has to be fitted with press.
Thank you once again.

Regards,
Nenad
