Timepiece movement and timepiece

A timepiece movement comprising:

• a stepping motor that has a rotor for rotating an indicating hand;
• a control circuit configured to apply a main drive pulse and an auxiliary drive pulse to rotate the rotor, detect a rotation state of the rotor when the indicating hand is rotated by application of a detection drive pulse based on the main drive pulse, and determine a reference position of the indicating hand based on the detected rotation state of the rotor;
• a train wheel configured to transmit a drive force of the stepping motor to the indicating hand, the train wheel having a first gear and a second gear which mesh with each other;
• and
• an elastic portion formed in the first gear, wherein the elastic portion is elastically deformed upon contact with the second gear when the indicating hand is located at the reference position,
• wherein the first gear includes an elastic tooth having a first tooth surface facing an upstream direction of rotation of the first gear and a second tooth surface facing a downstream direction of the rotation of the first gear, wherein the elastic portion comprises at least one of the first tooth surface and the second tooth surface.
