A device comprises a basic clock movement MB whose time indicators are driven by a first barrel connected to a first wheelwork and a first regulator organ, and an autonomous chronograph module MCA whose indicators are driven by a second barrel independent from the first, connected to a second wheelwork and a second regulator organ. The chronograph module is exclusively composed of mechanical elements. The frequency of oscillation supplied by its regulator is equal N times the frequency of oscillation supplied by the regulator of the base movement, with the coefficient N being definable according to a specific application of the chronograph, so that any chronograph module thus previously defined can work with the same base movement. The chronograph regulator remains constantly engaged with the corresponding wheelwork. The chronograph module allows a time interval to be read with a minimum precision of a hundredth of second. The organs of the base movement and of the chronograph module are arranged in such a way that in assembled state, the height and overall diameter do not exceed 7.75 mm and 30 mm respectively, the dimensions of the chronograph itself being not greater than 4 mm (height) and 30 mm (diameter) when its elements are mounted on a bottom plate, so that the device can advantageously be integrated in the case of a wrist-watch and affords an aesthetic exterior.

Device comprising a clock movement and a chronograph module

Timepiece including indicator members actuated or not actuated by the movement. These indicator members are composed of movable hour marks represented by the faces of the studs () mounted on staffs having planet wheels () driven by a rack (). The faces of the studs carry stones of various colors. When the movement operates the rack, it determines the change of the hour marks. When operation by the movement is disengaged, manual control elements allow the hour marks appearing on the dial to be changed.
