Thread: 5 digit vs 8 digit reference numbers.

    5 digit vs 8 digit reference numbers.

    We have never come up with a defintive date as to when Rado started changing from 5 to 8 digit reference numbers. I tend to say 1973-ish, knowing we have some indications that the 8 digit references started in 1972. We have come upon that by checking the movement codes.

    I think it is also fairly well established that watches with both reference numbers finished production in 1974 and all subsequent models carry only the 8 digit code.

    I have recently been perusing some model name/ reference number data that I got from a HIGHLY reliable source. I stumbled upon an interesting tidbit. TheMusketeer IX, reference number 625.3120. 2 and 625.3120.4 and the Silver Stag, ref 623.3117.4/2 and 625.117.4/2 were all released in 1971 and do not have a 5 digit code. I have however seen numerous models released in 1971 with both, so it seems these four models are some of the very first 8 digit only references.

    Great sleuthing Hank! It seems they were running the 5 & 8 digit reference systems for some time, both separately & occasionally together. As we so often find with Rado, the rule is that there will always be exceptions to the rule.

    Yes. At least four years now.I have yet to see any models issued in 1970, so I don't know if there are any watches dating before 1971 that carry both reference numbers.
