Snagged this from eBay at what I felt was a BIN price too good to pass up ($1500). Solid 18k chronometer, rare case reference (14311), and original dial. I've seen a handful posted here, but I do not see consistency in the crowns and none look like the replacement shown at Otto Frei. Suggestions on what I should be looking for appreciated.

 

Congrats... A rare catch in this original condition.

Here is a very comprehensive thread on this watch reference, just in case you hadn't seen it before:

Thanks. I am familiar with that thread, and I suspect the one shown is the crown I need. However, others posted have different Omega crowns and I would like confirmation on which is correct.

 

I have a 352 18k snap back case non waterproof and the crown looks like this.

 

I don't think so. It is too small and the design is a later one IMO.

 

4.5-mm in diameter and 1.8-mm deep.

 

May I ask you @X350 XJR , is the crown of the watch in the linked thread correct in your eyes or not? I'm trying to learn a bit about this reference and any help is more than welcome.

 

Looks like the same crown as the one I posted and I have seen this crown more times than not on this reference so I believe it is the correct one.
