What happened to this one?


And yes the Gravina example looks Rose to me-
This is the pic my opinion is based on

The seller would not post me a photo of the inside of the back, or provide the case number. Seems odd, but there you go. One of you blokes will have to buy the watch (don't look at me, I'm on a pension . . . )

Well, we've only got one engraved back, so far. I have added it to the comments column as "EB" for now. And I have made the Doug Gravina (10785584) RG in the table.

 

Here you go, table update -

 

Unless they were Descending.

 

Here's another:
18KT ROSE GOLD, CASE # 10785645 2500, CALIBER JUB 30.10, RA RC, SERIAL # 10,761,445
It's got the Centenary engraving

Thank you both for the detective work! The updated table is here, with the new entries highlighted in yellow -



The rose gold cases are still staying together in a nice batch (I think pitpro's watch may be the start of a second batch). And it looks as if the ones destined for the North American market might have had the "2500" case reference before any others. But the engraved backs are just scatter-gunned, with no obvious logic at all, except that we could say that they seem to be later rather than earlier. Which does not make any sense, because you would imagine that once you had started engraving the back that all subsequent cases would then have been engraved also. It does explain why the engraved examples are so rare, though.

 

It looks like we have run out of examples, for the moment anyway. Despite the very small sample, I think that the table is still quite useful to give an idea of where a particular 2500 fits within the sequence. As new watches come on the market, I will keep an eye out for them and add them to the table. Here, for now, is the final version with engraved back (EB) given its own column



Now I must get back to the search for my very own Centenary!

 

Interesting that all Engraved Back Centenaries are fall within 1078XXX case number and 1075XXX & 1076XXX movt number

 

Yes, in general the engraved backs seem to be later rather than earlier, but that is probably as much as we can say. What you can definitely say is that they are quite scarce. The real shame is that most watches got separated from their chronometer certificates, so we have no idea how those edition numbers went.

 

Here is mine. I bought it from US. No engraved case back. Yellow Gold. Caseback number 10784912 and Movement number 10760572.

 

Aha, Pday7, I was hoping we might get your personal Centenary! I will add it to our table - that is actually a very nice example.

Thanks very much for posting

 

You are very welcome. Thank you for developing Centenary reference. Certainly many centenary hunters in the future will revisit this thread for their reference.
