Abstract
The invention relates to a base element for a wristwatch in the form of a laminate, which simultaneously serves the purpose of a movement plate or frame and a case back and which consists of two integrally joined plates, these plates being bonded together in particular by means of a foil using ultrasonic heat-sealing. Such a base element may be manufactured with high precision simply and cheaply and has good stability, especially when a circular edge is folded to the inside of one of the plates of the base element for the purpose of reinforcement.
