Nivada Chronometre Serial Numbers
NIVADA OFFICIALLY CERTIFIED CHRONOMETRE SERIAL NUMBERS
It is hoped that here on Chronopedia we can create a list of serial numbers issued to these watches. Each model sold originally had a paper certificate which matched the serial number on the movement. Most of the paperwork has been lost over time, sadly. However the majority of observed examples do carry a 1 to 4 digit code in addition to the movement reference, normally the ETA 2452, later 2472, engraved on the movement which enables us to catalogue and date them. This is also a good way to assess that the watch is original and has not been altered or made up from lesser parts.
The NAOCC model seems to have been issued late 1958 and was still being marketed in 1965. There are exceptions to this but the majority of observed examples carry the number. The Rudolphs Dependable OCC version, marketed by Croton in US, does have an individual number on the movement on the few examples seen. It has a slightly different case with a semi concealed crown.
It seems the NAOCC was sold both in North America and Europe with the Nivada Grenchen name and not the Croton Nivada Grenchen branding more typical of the North American market. Note also the spelling of Chronometre in European style.
The number is engraved in the location shown in the movement shot here:
