Abstract
Clockwork movement for a wristwatch, comprising a kinematic chain including at least one belt (20, 21) for transmitting the movements and/or couples between at least two pulleys. The pulleys are held on the bottom plate or the bridges by ball bearings (151, 161, 171, 181). The movement is rewound by means of linear oscillating mass (14) charging four barrels (15, 16, 17, 18) through a couple distributor (40). The barrels are non-parallel to one another. The back cover is covered by inclined glasses (110, 120, 130) allowing the barrels, the linear oscillating mass and at least certain pulleys to be seen. The regulating organ (51) is removable.
Claims55
A clockwork movement designed to be integrated in a case of a wristwatch, said movement comprising:
- a bottom plate;
- one regulating organ fastened on a first side of said bottom plate;
- at least one barrel mounted on said first side of said bottom plate;
- a kinematic chain, said kinematic chain comprising at least one belt for driving one driven pulley held on said first side of said bottom plate;
- at least one circularly rotating hand on a second side of said bottom plate;
- and
- at least two barrels connected to one another by means of belts;
- wherein said belt transmits movements and/or couples to said pulley in order to modify an angular position of said hand.
A clockwork movement designed to be integrated in a case of a wristwatch, said movement comprising:
- a bottom plate;
- one regulating organ fastened on a first side of said bottom plate;
- at least one barrel mounted on said first side of said bottom plate;
- a kinematic chain, said kinematic chain comprising at least one belt for driving one driven pulley held on said first side of said bottom plate;
- at least one circularly rotating hand on a second side of said bottom plate;
- and
- four barrels visible on the lower face of the movement and distributed in two pairs of two barrels, the barrels constituting each pair being connected to one another through a belt, both pairs of barrels being connected to one another through a couple distributor;
- wherein said belt transmits movements and/or couples to said pulley in order to modify an angular position of said hand.
