Omega Constellation Manhattan 398.0864 Cal 1422 glass replacement

Archer

It's just a plain sapphire glass - nothing printed on it.

062SN5071 - GLASS SAPPHIRE D25 H0.8

I used the numbers you provided - that number is for a different watch than yours then. Can you provide another case back number, reference number, or serial number?

Okay - I used the bracelet to get to a bunch of different watches, and I think I found yours. The case number is 055ST1980136, so inside the case back there will likely be 1980 136. You would need to verify that to be sure the information I'm giving you is correct.

On this model there are 2 crystals - one that covers the dial and one that acts as the bezel.

The first crystal that covers the dial is the same one I listed above - 062SN5071 - GLASS SAPPHIRE D25 H0.8.

The second one that goes over that, and is held by the claws, is:

062SZ0556001 - GLASS SAPPHIRE TRANSF D31.5 H0.8

That number is a subassembly of a crystal and a titanium ring.

062SN0556 - GLASS SAPPHIRE D31.5 H0.8

076TI0120 - RING TITANIUM

To be honest, I don't know what these models go for, but my impression is that they are not terribly sought after on the open market. The second crystal subassembly is around $500 US, which might be more than the watch is even worth, so just something to consider. Of course if the watch has sentimental value, that's a different thing...

The chances of you finding this crystal assembly out on the open market is, I imagine, very slim, but the part numbers should help you look at least.
