Notes
The 19.73N has instantaneous jumping minutes and both 30 and 60 minute counter versions of the movement were made. A Rattrapante version was also regularly made starting in 1922. Rarer variations include a double face watch with time displays on both sides, a 1/10th second version and even a 1/100th second version. "N" designation means a new version of an existing movement.
