Hi,

I would like to confirm my research on the internet. 17 jewel Valjoux 7750 was made during very short period of time, 1973 - 1975. Then in 1984 Breitling signed with Valjoux contract regarding supply of Valjoux 7750 for introduced Chronomat (1984) and Old Navitimer (1989). Were the supplied movements made in 70s or Valjoux started again production of these movements in the 80s and then replaced with 25 jewel ETA Valjoux 7750 sometimes around early 90s?

Thank you in advance for any relevant help!

Nobody knows? At this stage I think that 17 jewel Valjoux 7750 was again produced in the middle of 80s.
