Info request on Gyromatic Chronometer HF, 39j,36000bph. caliber 42

Jan 21, 2007,23:59 PM

Good Day,

I am doing research on this vintage marvel of horology:
GP GYROMATIC CHRONOMETER HF, 39j, 36000 bph, caliber 42
with "suspension case" that GP introduced in 1968/70

I would really appreciate if Peter and other GP gurus
could email me with detailed history info and or articles
on above as well as scans of the various cases, dials and shapes.

Also any info in relation to the dial version with the Neuchatel observatory logo models
would be highly appreciated.

I am relatively new with GP but have found it to be a fascinating brand
past, present and definetely in the furure.

Awaiting everybody's assistance.

Thanks
Nikos

Hi Nikos, there´s no comprehensive list so far, but there´s a LOT of earlier posts on the fast-beat movements as well as various models of the "ChronometerHF" over the years. I´m confident you will find some input using the search function of this site As...

Thanks, Peter and one more question...

Any input on the "pressure case" you stated in earlier posts that was introduced by GP in 1968/1970. Did GP make any Gyromatic Chronometers HF with the 39j,36000, caliber 42 usinf this so special "pressure case"? Any scans or ref. nos available? Tks Nikos

This one?
