摘要

The wristwatch (1) has a wrist-watch strap (8) provided with strands (4, 6) and a flexible and extensible body, and an electronic clock movement (16) provided with components such as quartz resonator or microprocessor, mounted on a printed circuit board (42). A display unit (14) with a flexible liquid crystal cell or an organic LED, is controlled by the movement. An electric power source (12) is connected to the movement by a flexible and extensible electrical connection unit (54) incorporated in the body. The connection unit is constituted of coil shaped conductive wires (56, 58).
