Hey people,

I’m after a replacement crystal gasket for this, my watchmaker gave it a service but couldn’t locate a seal for me

Can anyone recommend a supplier for me, I’m in London

Generally speaking there's no easy source, you need to put in some effort and hunt. If your watchmaker can tell you the reference number of the watch, you can use the reference information in this thread to find the correct part number, and then hunt it down on the internet.

THIS is your crystal: https://www.ebay.com/itm/256799587938 (2105) according to the post Dan gave you.

It isn't listed as having a gasket, so I presume/assume it counts on 'tension' to not leak.

No? I'm not sure. BUT none of the watches with that crystal list a gasket, which is why I think that. Could the crystal you have be unoriginal? or worn to the point of needing the gasket (that a previous watchmaker put it in?)?

Those aren't really available unfortunately.

IMO, if it was me, I'd order a crystal based on that number (I found quite a few including less expensive authentics, and not-authentic ones on ebay), and 'see' what happens. Perhaps @Archer can check out the actual Omega extranet docs to see if there is a gasket listed for that, but if he doesnt/cant, I'd go from there.

I’ve just seen this however I’m in London so the shipping isn’t worth it but it does state gasket included

I see a few non-authentic ones in the UK, authentic in Canada and Germany. Also, cousins seems to have 6 in stock?

I did also but no gasket. I think I may have found one in the Netherlands

It definitely needs a gasket

As you can see mine is torn at the 2 o clock position

This doesn’t look correct, I think mine sits in a grove on the actual crystal?

Please no offense but that gasket looks like someone put it on with a caulk gun? 😬

Yeah, looking at that case, I'd assume the gasket goes 'above' the crystal. But with it broken, I wouldn't doubt that it was either installed incorrectly/'came out' at the same time as teh crystal and was placed in the wrong position for the photo.

Thats actually not odd of that sort of gasket. In my experience, they are basically one-use. Once you've squished them in/let them 'set' for a while, they end up doing... THAT whenever you try to re-use them.
