calibre 453 & 454 with Geneva Seal

I read an article said that  no matter whether the cl,453 or cal.454 with Geneva seal, they all reached the Geneva grade.

I still can't  understand it . There are two questions below.

1, calibre 453 & 454 with Geneva Seal or without Geneva Seal , When assembling is arbitrary, there is no law.  may be  two watches in same reference ,one stamped  Geneva Seal  , the other without it .   the calibre  with the Geneva seal  is the customer specially order it ?

2,V&C should be  pay for the cost of application for Geneva Seal . so watch with the Geneva seal  will be more expensive? Do you know how much is the price gap?

   thank you

I made a mistake, not serious. I mistake  chronometre quality  for geneva seal quality.

old disccussions about  "chronometre quality"  and "chronometre calibers"ètre-calibers-vc-540790


but some chronometre calibers have or not have genev seal,  such as cal.1003,453.454  ,etc.     they   fit in   the Geneva seal  standard.

 i still donot know why is it .

"Chronometre Quality" and "Geneva Seal" are two totally different things

"Chronometre Quality" as used in the German book that Doc referenced many years ago, does not have a specific/exact definition.  I understand it to be that those calibres were either:

1. at least one movement of that calibre was specifically regulated, tested, and passed Chronometer standards (i.e. sent to an Observatory and successfully passed the time trials) or

2. these were calibres that VC believed could pass Observatory time trials if regulated properly for that type of difficult testing.


The Geneva Seal standards are related to the quality of the movement, its construction, and appearance.  The Geneva Seal requirements did not include a time-keeping accuracy standard until just a few years ago (in 2008, when the changes occurred with the creation of TimeLab, an new organization that manages both Geneva Seal and Cnronometer standards...from COSC to a newly developed Chronometric+ Observatory Certification).

Alex has shared with us in the past that for many decades, VC did not believe the Geneva Seal was a priority and so did not require all of its movements to have the Geneva Seal.  Mnay of the classic, vintage calibres (i.e. 453, 454, 1003, etc.) could all meet the requirements for the Geneva Seal, but VC did not send each movement in for certification.  They would do it if a customer specifically asked for it. 

I do not believe there would have been a big price difference.  But I guess if a customer specifically requested a GS, they would pay for any registration fee.

thank you Dan.

i cannot understand  the word "GS"  in    But I guess if a customer specifically requested a GS, they would pay for any registration fee.

maybe S mean for service

GS = Geneva Seal (nt)
