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.
Claims51
Clockwork movement designed to be integrated in the case of a wristwatch and comprising at least one hand and a kinematic chain for modifying the angular position of said hand,
- wherein said kinematic chain comprises at least one belt and at least two pulleys, said belt transmitting the movements and/or the couples between said pulleys.
Mechanical clockwork movement designed to be integrated in the case of a wristwatch and comprising at least one barrel, at least one rotating hand and a kinematic chain between said barrels and said hands 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.
Clockwork movement for a wristwatch, comprising at least one rotating time indicating hand, at least one axis, said hand being mounted on said axis, and a kinematic chain driving said axis for rotating said rotating time indicating hand so as to indicate different time with different angular position of said dial,
- wherein said kinematic chain comprises:
- one driving pulley,
- one belt,
- one driven pulley,
- said belt transmitting the movements and/or the couples between said pulleys.
Clockwork movement designed to be integrated in the case of a wristwatch and comprising at least one time indicating rotating hand, said rotating hand being driven in rotation by an assembly of pulleys and belt.
Wristwatch comprising:
- a case,
- at least one glass closing one face of said case,
- a clockwork movement integrated in said case, said clockwork comprising at least one belt and at least two pulleys for driving a time indicating hand in rotation,
- at least one said belt being at least partially visible through said glass.
Clockwork movement designed to be integrated in the case of a wristwatch and comprising:
- at least one hand whose angular position is modified for showing a first time indication,
- at least one belt,
- at least one indicator borne directly by said belt for showing a second time indication.
Clockwork movement designed to be integrated in the case of a wristwatch and comprising:
- at least one belt tightened between two pulleys,
- at least one indicator borne directly by said belt for showing a time indication,
- one kinematic chain for driving one of said pulleys,
- said kinematic chain comprising at least one second belt.
