    There should perhaps be a column for engraved back, when known.

    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.

    I believe that Omega did their own chronometer testing until about 1951, when a change in Swiss law required the manufacturers to use outside testing agencies.

    Here is a thread (the author of the top post should be familiar to most of you), that discusses this relative to the Centenary models.

    http://omega.watchprosite.com/?show=forumpostf&fi=677&pi=5624973&ti=832198&s=0

    This information should be highly relevant here as well.

    A few more from around the net:

    This one has the most detailed picture of the movement, but no mention of the case number. You may be able to e-mail the author:

    http://ninanet.net/watches/others07/Mediums/momegas.html

    One that was sold and the pics were taken down. Has both the movement and case numbers:

    Another one that was sold and has both numbers:

    http://forums.timezone.com/index.php?t=tree&goto=5437554&rid=0

    One shown in another forum, pictures aren't too good, but there is a narrative:

    http://omega.watchprosite.com/?show=forumpostf&fi=677&pi=3620456&ti=581981&s=0

    http://omega.watchprosite.com/?show=forumpostf&fi=677&pi=3817821&ti=609281&s=0

    Another one from that forum:

    http://omega.watchprosite.com/?show=forumpostf&fi=677&pi=2387146&ti=399681&s=0

    I think the movement is 10,760,600 and case is 10,784,090?

    A completed eBay auction. Good pictures of a bad redial, engraved also:

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

    2500 Table 6-5-14.jpg

    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

    2500 Table 7-5-14.jpg

    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.

    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 :thumbsup:

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