From Chronomatic to Quartz
Posted by: David Chalmers | 18 January 2013 | No Comment
The original Chronomatic movement was quickly upgraded, with new Calibre 12 and low-cost Calibre 15 variants added, as well as the manual wind Valjoux 7733, 7736 and 7734 (all descendent of the Venus 188) movements
The quartz movements were supplied by ESA, which was later re-named ETA. In addition to consuming ESA, Valjoux was also part of the ETA empire.
