Here are images 30.10ra 1 30.10ra 1...  

Hi Brian, the pictures tell it all:  model "Centenaire"  Chronometre from 1948, Ref. 2500 This ref# is not always found in the case back but it is ref 2500 without any doubt! Does it have the additional "JUB"  behind the 30.10 RA (found below the balance)... 

Dear Erich, Many thanks..you made my day!!!! Regards Brian

does it have a laurel wreath engraved on the caseback? i was hoping you'd show a pic of it, but as you didnt i'm guessing it's a plain back. perhaps not all Centenaries had the Laurel Wreath on the back. Erich should be able to confirm this. best Graham

Thanks your message. No wreath on back.. But I now can see that it has "JUB" written underneath balance, thanks Erich for the advice!! Regards Brian

of ref. 2500 without the laurel leaf centenary inscription on the back than pieces that did have it. The ref. number 2500 is also typically engraved in the watches of later production - frequently those that had the cal. 333 instead of the cal. 30.10 JUB

interesting to know MSN. is there any rhyme or reason to which had the engraving on or was it just random? best Graham

that I've seen are usually for the South American market though I am not aware of whether the presence of the engraving was dictated by market considerations.

. . . and as close to perfect a formal watch can be . . . very, very nice. Cordially, Art

... of a truly beautiful and gentlemen like watch. Thanks for sharing the pictures. For the rest of the bunch: Thanks for your thoughts and learning points Best Hans
