To provide a timepiece movement of an analog chronograph timepiece capable of fan-shaped display with a simple structure, while using in common a heart cam which is difficult to be processed.

A restricting pin 16 is pressed and fixed in a gear train base 6, to thereby prevent the phase of the heart cam 4b from being deviated up to an irreversible domain. A projection part 8d is formed on the tip part of a return-to-zero lever 8 for zero-returning the heart cam 4b, to thereby acquire a structure wherein the heart cam 4b is reversely zero-returned without fail. Therefore, a structure can be acquired, wherein the heart cam 4b which is difficult to be processed is used in common, and the retrograde chronograph can be reversed simply and surely. In addition, the gear train base 6 is used in common with another product, thereby realizes common use of the component for products having a plurality of specifications to thereby reduce cost.
