摘要： A multifunction timepiece (1) comprises a rate regulation means provided to regulate the rate while maintaining the rotation of a gear train (20) in a fixed direction. The driving speed of the gear train (20) is not brought to zero even for a moment, and each CG hand and a second hand perform sweep motion. Since the measured time can be known quantitatively even if the stopping position of each CG hand is not graduated, a more accurate measurement can be realized. Since sweep motion is employed, interval of graduation (arrangement of graduations) for the second CG hand on the dial (7) is not limited. Further and since finer graduation can be realized, minimum measurable unit can be made smaller.

摘要： A timepiece (1000) having an ordinary time measuring section (1110) for measuring an ordinary time and time information measuring sections (1210,1220,1230) for measuring time information other than the ordinary time is characterized in that the parts, which constitute the ordinary time measuring section and the time information measuring section, are entirely or partly disposed without overlapping on the same plane.

摘要： 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).
