Abstract

A timepiece movement main body (6) constituting a base unit (2) of a chronograph function attached timepiece (1) includes a barrel complete (20), a center wheel and pinion (24A) rotated in accordance with rotation of the barrel complete, a third wheel and pinion rotated in accordance with rotation of the center wheel and pinion, a fourth wheel and pinion (36) coaxial with the center wheel and pinion (24A) and rotated in accordance with rotation of the third wheel and pinion, and a minute transmission wheel (80) slippingly engaged with the center wheel and pinion (24A) on a dial side of a main plate (10) brought in mesh with minute wheels (60,62). The minute transmission wheel (80) is a wheel in a shape of a flat plate, engaged with the center wheel and pinion (24A) at an elastic engaging portion of a center thereof, and slipped when the elastic engaging portion achieves a predetermined or more torque.
