っていた。[Detailed Description of the Invention] [Summary of the Invention] Conventional magnetic circuit holding plates, gear train bridges, and base plates are susceptible to damage caused by the drive body (coil,
(magnetic core, stator) becomes magnetized and ceases to function. To solve this problem, a soft magnetic material is placed between the move and the exterior, but this results in a double structure, which increases costs and increases the outside diameter.

する外部電磁界から駆動体を保護する様にした。By providing a shielding function to the watch parts themselves, such as the circuit retainer, gear train bridge, and main plate, it is possible to reduce the cost and reduce the external electromagnetic field generated in daily life with the same outer diameter as a conventional case. This protects the drive body from

ストアップにもつながった。Conventionally, the material used for shielding function is pure iron, Fe-N.
Since it is made of i-alloy and silicon steel, it has been difficult to use it for circuit holding plates, gear train bridges, main plates, etc. due to problems such as poor strength and easy rusting. Providing the shield layer 1) inside the case increases the size of the entire case, making it difficult to make it smaller and thinner. Furthermore, the need for shielding components also led to an increase in costs.
