Title:
ELECTRONIC CONTROL TYPE MECHANICAL WATCH
Document Type and Number:
Japanese Patent JP2022061699
Kind Code:
A
Abstract:
To provide an electronic control type mechanical watch that, even when large impact is applied to a bearing of a rotor, can prevent coming-off of an end stone and damage to a pressure bar spring.SOLUTION: An electronic control type mechanical watch comprises: a rotor 81 that includes a rotation shaft 82 having axles 821, 822 on both sides, a pinion 83 provided on the rotation shaft 82 and to which torque from a power spring is transmitted, and a rotor magnet 84 attached to the rotation shaft 82, and is rotated by the torque; a bearing 100 that includes a frame body 110 fixed to a bottom board 11, a hole jewel 120 fixed to the frame body 110 and having a through hole through which one axle of the rotation shaft 82 is inserted, an end stone 130 arranged in the frame body 110, and a pressure bar spring 140 holding down the end stone 130, and pivotally supports one axle; and a stopper 86 that is attached to the rotation shaft 82 and has a contact part brought into contact with the hole jewel 120 when the rotor 81 moves toward the bearing side.SELECTED DRAWING: Figure 5
