New to Omega

Rhinoww · Nov 25, 2025

Hi
I just picked up this gem (please excuse my dirty mat)

With decently healthy beat, consistent with a relatively recent overhaul.

The crystal was not replaced and has some chips and scratches but appears serviceable after a cleaning but I will still likely replace it in the next few months.

The case back gasket seemed ok, but did not strike me as new

This gets me to the pushers - I’m new to omegas but have quite a few Seiko chronographs. The pusher gaskets there are always hard and need to be replaced. Is that also standard for Omegas? I took a quick spin on the web and candidly did not see many options OEM or other (I’m find with other from a reputable seller).

Should I prioritize replacing the pusher gaskets (and if so I’m very open to hearing about retailers) or is it a nothingburger given the pusher design.

I never submerge any vintage watch unless everything on the outside is screw down so this is more of an incidental water hazard I’m trying to avoid.

Thanks.

Just FYI the lift angle is 50 on this movement so the amplitude you see there is artificially high by about 10 degrees or so, so if that is horizontal full wind, it’s pretty low for any sort of recent service.

Omega doesn’t typically sell pusher seals separately, so they intend that the entire pusher is replaced. That’s why you won’t typically find seals for these on the open market. Same for the crown.

Thanks. Super helpful.

Is there a particular reason why one wouldn’t want to replace the gaskets rather than the entire pusher? Are the gaskets a challenge to get to/get properly installed or seated?

That's the way Omega does it - I can't speak for why. If you can find the correct sized seals, then they are not difficult to replace.

There is a seller on eBay with a full rebuild kit which includes gaskets for the pushers - but that’s the only place I have seen them.

Try them and let us know if they work. The key is getting the correct size, and pressure testing it after to ensure that they work.

In my experience, the smaller O-rings for crown, case tubes, and pushers, are much more limited in the range of sizes that are available than for the larger case back O-rings. Some of the larger O-rings I can get in 0.1 mm increments in diameter, and in cross section. For the small O-rings, they usually come in assortments that have a few sizes, and anything more than that is a real search to find - and the fact that the size required is not known (directly from Omega as they do not say) doesn't make things easier.

I've had a few people here tell me they replace the seals, but they have never disclosed what sizes they use, or if the watch passes the pressure testing once they are replaced. Since I service other people's watches for a living, and provide warranties, I need to know for sure that it works, so I am in a different position than someone just repairing their own watch...

I’ll order and report back on the pusher gaskets. No tooling to check on whether my fix will stand up to pressure though - while nice that’s really not my ultimate goal which more to prevent accidental water incursion.
