Omega Constellation 168.0058 Crystal Gasket Source

g60rge · Sep 17, 2026

Guys is a 50 year old gasket it’s gone sticky and goey hence why I’m asking for help to replace it

From the one I’ve see online it slides over the lip on the crystal to seal both sides between the crystal and rear case and the crystal and upper case. Am I right?

This makes me believe I have the wrong one all together

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

It sure does

picking up one of the crystals-with-gaskets will likely be VERY informative 😀

Thank you that’s very informative

However you are now no longer waterproof 😂😂

Is the seal on the top side of the crystal also?

Not worn in a few years I should really give it a little wrist time

Ah well I wouldn’t trust any of my watches with water anyway lol

I don’t believe this is waterproof or resistant anyway
It’s a weird setup the crystal just rests on the movement and the press into to case with the 4 screws holding it all together

I have no other gasket or seal

Isn't that the movement 'in' the caseback? So the gasket is crystal-to-caseback and crystal-to-case-front? Thats a pretty common case design that can be waterproof.

I just made a purchase, expensive piece of plastic but it’s probably one of the last ones in the world 😂

It comes with the gasket

Will update when it arrives

I guess any water that gets in between the crystal and front case just runs out the back of the watch

Yeah, i think that is the idea. I have a square seiko I did work on that is effectively the same thing.

That’s how I felt about mine but I went to wash my hands one day and I saw a drop of water get inside. Accidents happen so I’d rather make it as good as I can

yes I guess so, it’s got a split stem design also but I wouldn’t trust mine nore how water proof or resistant they actually are
If serviced correctly properly totally fine in a light shower
People often get confused with the terms water proof and water resistant
I definitely won’t be swimming with it

But then obviously you’re got the risk of moisture / condensation being out in the sun and then going into a air conditioned room will cause condensation inside

With the logo in the centre?.

I’d say that’s a very fair price tbf

Crystal is 062PN2105, and if you want just the seal, that is 088NA0102.

Any Omega certified watchmaker has access to these parts directly from Omega.

Also if you are concerned about water intrusion, you might want a new crown also - 069ST42530.

Lastly, the crown seals on the case tube, and I often find these tubes worn on vintage watches, so the new tube is 090ST4027.

Well guys, it looks like we’re in business!
