The image (from MikeyT) is the caliber 426, a 15 jewel movement that is tonneau-shaped and 9-3/4 ligne or 22mm in size. The caliber number is clearly stamped next to the balance wheel on the pillar plate. This is similar to the 425 (17-jewels) and like others in the 405-caliber series interchanges almost completely with the other 15-jewel versions.
All I know is based on hard work & writing by others. I can only aspire to augment this body of knowledge. If I am wrong it is because of my own failings. -me
