Hi, could someone tell me where to get a new case gasket for this watch, from what I can see its ref. 088NS5081 or #088-0800 or 088.5081NS
Confusing on cousins it says its 31.6mm x 0.8mm but it says it dosnt sell them as they are an official omega item. Ive been scouring the Internet for the correct gasket but cant find one in the UK. I have a bag of gineric o ring gaskets I tried a 31mm x 0.7mm but it just pops out and it no good. Your expertise and experience is needed. Many thanks.

If you post the case number I can check if this is the right O-ring, but the dimensions for it are:

088NS5081 | SEAL O-RING d30 D31.6 ø0.8

Where
Any simple O-ring with the same dimensions will work.
Where would be the best place to get one?

Have you tried using Google? If so, and you came up empty, then contact the watch material supplier that is nearest you...
