Abstract:
A watch includes a power reserve hand configured to be visually recognizable from a watch rear side, an oscillating weight including a weight, a transmission wheel configured to rotate a ratchet wheel, a pawl lever configured to engage with the transmission wheel, an eccentric wheel including an eccentric shaft member to which the pawl lever is attached and an eccentric toothed gear, a train wheel bridge provided between the pawl lever and the oscillating weight, and a seconds wheel and pinion including a seconds hand shaft. The eccentric shaft member and the seconds hand shaft are supported by the train wheel bridge. The power reserve hand is disposed in a position that does not overlap the weight in plan view, and is disposed in a position that overlaps the train wheel bridge in side view orthogonal to the seconds hand shaft.
