The below is a caliber 405, 17 jewel movement and is marked next to the balance wheel with the caliber number. Size is 10x11 ligne or 22.56mm x 24.81mm.

This one is a later version of the 405. In most catelogs the 405 movements are divided into old model and new model and dealt with a variation of the setting bits and a change in the set stem. The above is an 'OM' 405 and the following is the 'NM' 405.

It should be noted that the calibers 406, 410, 411, 420, 421, 425 and 426 are all based on the 405. Difference is mostly round or tonneau-shaped movement.


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
