Calibre 12 with chronograph

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.
