<p>PROBLEM TO BE SOLVED: To provide a balance spring support adjustment mechanism that can independently adjust the pulsating and rate without causing the pulsating misalignment due to the rate adjustment and rate misalignment due to the pulsating adjustment, and can perform coarse adjustment of the rate.SOLUTION: The balance spring support adjustment mechanism includes: a regulator seat 60 disposed rotatably about the central axis C of a balance; an indexing device 70 that is combined with the regulator seat 60, can rotate about the central axis C with the regulator seat 60 in accordance with the rotation of the regulator seat 60, and can relatively rotate about the central axis C together with respect to the regulator seat 60; and an operation unit 80 that is rotatably attached to the indexing device 70 and can operate so as to rotate the indexing device 70 about the central axis C by a predetermined unit with respect to the regulator seat 60.</p> |
