Power reserve display mechanism and mechanical timepiece having the same

Abstract

To provide a power reserve display mechanism having a mainspring remaining amount display showing a novel behavior and a mechanical timepiece having the same. A power reserve display mechanism of a mechanical timepiece includes a displacement conversion mechanism having a first rotation input portion coupled to a ratchet wheel and rotated in accordance with rotation of the ratchet wheel and a second rotation input portion coupled to a barrel wheel and rotated in accordance with rotation of the barrel wheel as well as an output portion moved linearly in one direction in accordance with rotation of the first rotation input portion and moved linearly in other direction in accordance with rotation of the second rotation input portion, and mainspring accumulating remaining amount display means provided at the output portion of the displacement conversion mechanism for displaying a mainspring accumulating remaining amount by a position along a linear line. The mainspring accumulating remaining amount display means is moved in parallel with an extended face of a dial on a side of the dial of the timepiece.
