··ΩF InvestiGatorIn one thread of John R Smith (https://omegaforums.net/threads/centenary-2500-jub-serial-numbers.12752/) a list of movement and case serial numbers was created mainly focusing on JUB models. Here we have a cal 333. I could not find information for the serial ranges, but is it expected to have this huge gap (107….. for the latest movement in the list) to the discussed example (121…..)?
The paperwork in the listing shows a 1952 testing date, which means delivery was likely 1953 or later.
