Abstract
A timepiece construction member comprises a timepiece frame, trains, a motor, circuit member and so on. A supporting member for keeping and securing the timepiece construction member is made of a spring plate. The supporting member is engaged with the plate at the periphery thereof and as a result, the timepiece construction member is secured by a simple means. It is possible to provide a securing construction having a high reliability and a small number of members. Further, since the supporting member also serves as the other operating member such as a battery plus terminal, it is possible to provide a small sized securing construction for members. Furthermore, since the members of the timepiece are in contact with an elastic beam of the spring plate, the members of the timepiece can be secured stably.
