Clock work movement for a wristwatch

A clockwork movement designed to be integrated in a case of a wristwatch, said movement comprising:

• a 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 a driven pulley on said first side of said bottom plate;
• at least one circularly rotating hand on a second side of said bottom plate;
• wherein said at least one barrel drives said at least one belt, which in turn drives said driven pulley, which in turn rotates said at least one circularly rotating hand.

A clockwork movement designed to be integrated in a case of a wristwatch, said movement comprising:

• a 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 a driven pulley on said first side of said bottom plate;
• at least one circularly rotating hand on a second side of said bottom plate;
• a linear oscillating mass for loading said at least one barrel;
• wherein said at least one belt drives said driven pulley, which in turn rotates said at least one circularly rotating hand.

A clockwork movement designed to be integrated in a case of a wristwatch, said movement 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 all 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.

A wristwatch comprising:

• a wristwatch case,
• at least one glass closing one face of said case,
• a clockwork movement integrated in said wristwatch case, said clockwork comprising at least one belt driving at least one pulley, which in turn drives a time indicating hand in rotation about a fixed axis, the at least one belt and at least one pulley located within the clockwork movement,
• at least one said belt being at least partially visible through said glass.

A clockwork movement designed to be integrated in the case of a wristwatch, said clockwork movement 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,
• one driving pulley for driving said belt,
• one driven pulley driven by said belt and modifying the angular position of said hand, ball bearings,
• at least one axis for mounting at least one of said pulleys,
• at least one of said axis being held by and pivoting between said ball bearings.

A clockwork movement designed to be integrated in the case of a wristwatch, said clockwork movement comprising:

• at least one time indicator and a kinematic chain for modifying the position of said time indicator, wherein said kinematic chain comprises at least:
• one toothed belt,
• one driving pulley with a plurality of teeth for driving said belt,
• one pulley with a plurality of teeth and driven by said belt and modifying the position of said time indicator.

A wristwatch comprising:

• a watch case;
• a dial;
• a clockwork movement in said case, said movement being at least partially hidden by said dial;
• at least one hand;
• a kinematic chain in said movement for driving said hand, said kinematic chain comprising at least one barrel, two toothed pulleys parallel to said barrel, and at least one toothed belt tightened between said pulleys, wherein said at least one barrel drives one of the two toothed pulleys, which in turn drives said at least one toothed belt, which in turn drives said hand;
• wherein at least one said toothed belt is disposed in a plane behind said dial, and wherein said dial comprises an opening allowing said belt to be seen when the wristwatch is functioning.
