The logical slowing/speeding method is the mainstream, but future trends in the trimmer capacitor method are as follows: 1. The price of the trimmer capacitor is high, which will be an obstacle to reducing the cost of watches.

緩急スイツチ構造にするものである。<Problems to be solved by the invention> In principle, such a conventional structure is easy to adjust and has reliable electrical contacts, but it has the following drawbacks in processing. That is spring member 3
requires a certain amount of contact pressure with the patterns 2a, 2b, and 2c, and therefore has an initial deflection. When this spring member 3 is set to be caulked and fixed to the adjustment shaft 5, it takes the shape of 3a in the free state, and must be caulked while bending this. In the case of this kind of caulking,
Since the spring member 3 deforms at the caulked portion 5a and tends to warp up, it is difficult to ensure contact pressure with the initially set circuit board pattern. or,
As for the circuit configuration, the circuit board uses expensive MOSIC,
They often include elements such as crystal oscillators,
If the speed/speed switch becomes defective, they must be sacrificed. The present invention improves these drawbacks by making the speed/speed switch removable from the circuit holder, and provides a simpler and more reliable speed/speed switch structure.
