Abstract:
1. A clock having at least one driving element and at least one braking element, wherein the braking action of the braking element is based on a hydrostatic gradient of at least one flowable medium, wherein said driving element exerts a first torque (M 1 ) on a first shaft ( 10 ) extending along a first axis (A—A) and said braking element exerts a second torque (M 2 ) on to first shaft ( 10 ), said second torque being opposed to the first torque (M 1 ), wherein said braking element has at least one drum ( 20 ) which is rotatable round a second axis (B—B) and in which said flowable medium is located, and wherein said drum ( 20 ) is coupled to the first shaft ( 10 ) for rotation.
