Centenary 2500 JUB Serial Numbers

John R Smith

Well, I may indeed have to expand my study to the second series 2500 with the cal 333 (with the mythical RG regulator). So far there are only two examples, though, so we'd have to improve on that 😉

Just to keep you going, here is the updated table for the 2500 JUB -

You can see that the new entries are still fitting nicely into what must surely be a chronological sequence, with the "2500" case engravings all stacking up at the end. And Pitpro's example at the very end starts a new sequence of 10,8xx,xxx numbers, which I had not anticipated. What it seems to imply is that the movements are also chronological, but only as batches - so the 10,6xx batch are fitted altogether (but not in numerical order) then the 10,7xx batch (again, not in numerical order) and then presumably a 10,8xx batch. But we don't find 6s, 7s, or 8s mixed up together.

It would be nice to find earlier or later examples, just to confirm things.

Will find mine and post if you want.

My first watch for 2020 is also my first gold case watch (does the 50th anniversary Apollo XI Moonwatch count?). I read this thread many times over before committing to buying this one. Thanks!

(unfortunately my crown is a replacement-any information where I can find an original one?)
