Northern Irish master watchmaker Stephen McDonnell devised the world’s longest balance staff for MB&F’s LM Perpetual. It traversed the entire movement, leaving the large balance wheel on the front of the watch while moving the remaining parts of the escapement (anchor and escape wheel) to the opposite side of the movement, thereby splitting the escapement.
LM Split Escapement EVO highlights McDonnell’s genius idea. The manual-winding, 298-component movement is driven by double barrels providing 72 hours of power reserve and features a user-friendly, foolproof rapid date-changing system that prevents the user from inadvertently damaging the movement when adjusting the date.
It comes in MB&F’s titanium EVO case, which debuted in 2020 and was designed for an active lifestyle. It has 80 meters of water resistance, a screw-down crown, an integrated rubber strap, and a bezel-free design.
