Abstract

The invention relates to a power reserve indicator mechanism (1) for a timepiece, including: a threaded pin (2) intended for being mounted secured to a case element of said timepiece; a cam (3) having an outer surface (7) tilted relative to said pin (2), the cam (3) being arranged such as to engage by screwing with the threaded pin (2); a driving mobile (10) of said cam (3), said driving mobile (10) being intended for being rotated in both directions of rotation by a barrel of said timepiece, and including at least one means for rotating (4) said cam (3), secured to said driving mobile; a sensor (5) in contact with said outer surface (7) of said came (3) and kinematically linked with a power reserve indicator.
