ABSTRACT:
The skeleton watch of this invention includes a caseband (1) bearing a frame (6) arranged between an upper crystal and a back cover (26), a leg (8) contiguous to the frame, a motor (10, 11, 12) secured to the frame and including a rotor directly driving a minutes wheel (15) bearing a minutes marker (17). An hours hand (18) is driven by the minutes wheel through motion work including a train of planetary gears (23, 24). Zones (27 to 32) and conductors (33 to 37) are metallized on the internal face of the back cover and are intended respectively to accommodate the electrical and electronic components and establish connections among such components. The arrangement as set forth permits a greatly bared skeleton watch with a minimum of noticeable elements.
