With Legacy Machine Perpetual, MB&F and independent watchmaker Stephen McDonnell have reinvented one of the most complex traditional watchmaking complications: the perpetual calendar.
The result is Legacy Machine Perpetual, featuring a visually stunning in-house movement, developed from the ground up to eliminate the drawbacks of conventional perpetual calendars. The 581-component, fully integrated and purpose-built movement of Legacy Machine Perpetual has been designed for user-friendly and trouble-free use: thanks to an innovative “mechanical processor” (patent pending), no more skipping dates or jamming gears, and the adjuster pushers automatically deactivate when the calendar changes, so no problems there either.
