Hey everyone,

I recently bought a Constellation with the case number 143821.

Unfortunately the watch doesn’t have a genuine crystal on it. To keep things originally as possible iam on hunt for a genuine crystal now.

But which crystal do I need exaxtly? I have done some research so far. Is the number „PX5140“ right?

I need some assistance please 😀

PZ5140 for a steel case. PX5140 for a gold case.

Difference is the colour of the crystal tension ring, which should match the case.

Case number 143821 comes up as "no results found" on the Omega Extranet...

No idea what the correct crystal is based on that case number.

He may very well mean that, but I'm not guessing, so he'll have to clarify...

Actually, it's listed as "Restricted". which means you and I can't have it.
