A mechanical clock has a driving element and a braking element. The braking action of the braking element is based on a hydrostatic gradient of at least one flowable medium. The driving element exerts a first torque on a first shaft extending along a first axis, and the braking element exerts a second torque on the first shaft, with the second torque being opposed to the first torque. The braking element has at least one drum which is rotatable around a second axis and in which the flowable medium is located.
