Depth gauge watch e.g. diving watch, has electronic depth measurement module, placed below movement, coupled to depth gauge hand by transmission units circumventing movement periphery, where movement is autonomous and powered independently

摘要

The watch has a base plate (12) placed below a mechanical movement (1), and a display module (8), with a depth gauge hand (46), placed on the movement. An electronic depth measurement module (11), integrated to the plate, is connected to the hand by transmission units (30) circumventing the periphery of the movement. The units (30) have an electric motor (32) whose wheel meshes with a shaft (33) which is connected to the hand by an intermediate wheel. The module (11) is powered by a battery, and the movement is autonomous and is powered independent of the module (11).
