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.
Claims6
A wristwatch comprising:
- a case;
- a mechanical clockwork movement integrated in said case and comprising a plate;
- a glass;
- at least one circularly rotating hand between one first side of said plate and said glass;
- said movement comprising a plurality of components mounted on a second side of said plate opposite to said first side;
- said plurality of components mounted on said second side of said plate comprising a kinematic chain for modifying the angular position of said hand,
- wherein said kinematic chain comprises:
- one driving pulley,
- one belt,
- one driven pulley,
- said belt transmitting the movements and/or the couples between said driven and driving pulleys, wherein said at least one hand comprising:
- at least one time indicating rotating seconds hand for indicating seconds;
- at least one time indicating rotating minutes hand for indicating minutes;
- at least one time indicating rotating hours hand for indicating hours;
- wherein said at least one seconds hand, at least one minutes hand and at least one hours hand are being driven in rotation by a pulley, which in turn is driven by a belt, wherein said pulley and belt are located inside the movement.
