Cal. 57 is a cam-switching chronograph movement produced by Hahn & Cie. of Landeron in the 1950s. It was based on Cal. 51 as part of the large Cal. 48 family, and features a full calendar like the similar Cal. 59 but is slightly larger at 14 ligne.

Adjustment of the calendar is handled by pushers in the case:

  • 1:30 – Month
  • 4:30 – Date
  • 10:30 – Day
