Cal. 50 was an early three-button cam-switching chronograph movement produced by Landeron (Charles Hahn & Cie.) It is closely related to the three-button Cal. 47 and unusual column wheel Cal. 49.

Nicolet used Cal. 50.

Like all movements in the family it uses Heuer-style oscillating pinion rather than a traditional horizontal clutch to activate the chronograph function.
