Abstract

See full text

A mechanical clock movement includes a resonator, an escapement linked to the resonator, and a display of at least one item of time information. The display is driven by a mechanical drive device via a counter wheel train, the work rate of which is set by the escapement. At least the resonator is housed in a chamber, in which a reduced pressure in relation to atmospheric pressure prevails. The escapement is a magnetic escapement including an escape wheel coupled directly or indirectly to the resonator via a non-contact magnetic coupling system, wherein the magnetic coupling system is formed so that a non-magnetic wall of the chamber runs through the magnetic escapement so that a first part of the escapement is located inside the chamber whereas a second part of the escapement is located outside the chamber.
