About

Legacy Machines are wondrous reinterpretations of significant horological inventions by the greatest watchmakers in history. So the contemporary look endowed by the otherworldly appearance of Legacy Machine No.2's dual flying balances, suspended high above the dial from four gracefully arcing arms, may at first appear paradoxical. But make no mistake; LM2 is a timepiece tracing its lineage back over 250 years to three of the greatest watchmakers who ever lived: Abraham-Louis Breguet (1747– 1823), Ferdinand Berthoud (1727– 1807) and Antide Janvier (1751– 1835).

These horological legends of the 18th century are united not only by their inventive genius, but also by the fact that they have all constructed clocks and watches with two balances. Oscillating on high, the exalted double balance wheels of LM2 were inspired by one of the rarest mechanisms in the history of watchmaking: the dual regulator. And rarer still, the average rates of Legacy Machine No.2's dual regulators are transmitted by a differential to a single gear train, where the majority had two separate movements.

On display under a domed sapphire crystal cupola, the dial of Legacy Machine No. 2 is an object lesson in symmetrical simplicity. Top to bottom: the white stretched lacquer sub dial at 12 o'clock, with its blued gold hour and minute hands, is visually balanced by the large, raised differential at 6 o'clock. Left to right: the two flying balances and their escapements are identical mirror images, right down to the position of the stud holders pinning their balance springs.

While the levitated oscillating balance wheels of the binary regulators catch and hold the viewer's gaze, it is the large planetary differential sitting proud of the dial that is the real heart of Legacy Machine No. 2. In an incredible feat of micro-engineering − and the sheer paucity of timepieces with multiple regulators connected via a differential attests to the enormous difficulty in creating such a complex high-precision mechanism.

Immaculate Geneva waves, gold chatons, mirror-polished bevels and bridges designed with deliberate internal bevelled angles showcase the movement's peerless fine finishing. Consistent with MB&F's spirit of transparency, the names of the two men responsible for the movement (Jean-François Mojon and Kari Voutilainen) are hand engraved on the back.

Two and a half centuries after three of the world's greatest watchmakers put two balance wheels into their movements, MB&F celebrates their pioneering works by creating LM2, a timepiece with two balances hovering outside the movement.

Winding

Your watch is equipped with a manual winding movement, offering approximately 45 hours of power reserve. To wind it, keep the crown in position “in”; gently revolve the crown until you reach the maximum power reserve capacity (the crown will not turn more).

Time setting

Pull crown to position “out” and turn the crown to set the time. Push the crown back against the case when finished.
