摘要 |
The invention relates to a mechanical timepiece movement (2) including a resonator (10), an escapement associated with said resonator, and a display (8) of at least one piece of time information. Said display is driven by a mechanical drive device (4) via a counter wheel train (6), the operational pace of which is set by the escapement. At least the resonator is placed in a housing (14), inside of which a pressure lower than the atmospheric pressure exists. The escapement is a magnetic escapement (12) including an escapement wheel directly or indirectly coupled with the resonator via a contactless magnetic coupling system. Said magnetic coupling system is formed such that a non-magnetic wall of the housing passes through the magnetic escapement such that a first portion of said escapement is located inside the housing while a second portion of said escapement is located outside said housing. |
