A chronograph timepiece where elapsed time display sections can accurately return to zero and the number of parts is reduced to simplify the structure. The chronograph timepiece (1) has an hour CG wheel (25), a second CG wheel (40), and a minute CG wheel (60) that are separated from each other in the planer direction, and also has a hand return lever (160) for mechanically returning the hour CG wheel (25), the second CG wheel (40), and the minute CG wheel (60) to zero approximately at the same time. The hand return lever (160) has a hand return lever body (161) and a minute hand return lever (170). The hand return lever body (161) has an hour CG wheel operation section (164) and a second CG wheel operation section (165) that return the hour CG wheel (25) and the second CG wheel (40) to zero. The minute hand return lever (170) has a minute CG wheel operation section (172) for returning the minute CG wheel (60) to zero. The position of the minute wheel operation section (172) relative to both the hour CG wheel operating part (164) and the second CG wheel operating part (165) is adjusted by an adjustment shaft (167) of the minute hand return lever (170). |
