Hi all, I am collecting thin-style watches and just purchased a JLC steel which preceeded(?) the Master Ultra Thin series? ref. : 9124.42 case. : 1409204 cal. : 818/2 movement no. : 2207950 Does the movement correspond to the case number? Can anybody date movement or case? Thanks a lot for any info in advance. | ||

The movement does not correspond to the case #. The movement dates to about 1975, but I'm guessing here...I don't have pinpoint data prior to 1970. | ||

Hi Robert, this reference first showed up in 1975. So Zaf�s guess is very good. Ilja | ||

Thanks again to both of you. That's pretty close to the date I had given (mid to late '70). Nevertheless should I mention that ref# and case# were both impressed on the outside of the case. By comparing a few dozen ref/case# on eBay I must admit that I haven't understood the case-numbering scheme at all. I have found several correspondences as well as non-correspondences according to my watch. robert | ||

Hi. I'm not sure what you mean by correspondences. However, the case number is almost systematically lower than the movement number. That is, they are not supposed to match. Zaf | ||

Hi Zaf, I found several samples on eBay having a case number lower than the movement number e.g.: c#= 7xx.xxx / m#=1.2xx.xxx or c#=1.0xx.xxx / m#=1.7xx.xxx c#=1.4xx.xxx / m#=2.2xx.xxx (my watch) That's what I meant by using the term correspondence. Robert | ||

Well, that's what they should have. The case number is always lower than that of the movement. There is only one model where the case # and the movement # match that I am aware of, every thing else C# < M#. Zaf |
