MB&F celebrates the pioneering works of past masters and complications with Legacy Machine No.2.
Suspended high above the dial, the double “flying” balances are in fact the most visible parts of two fully independent regulating systems, each beating at its own rate. The planetary differential sits proud of the surface, supported by a stunning double-arc mirror-polished bridge. The complex differential is the key element in the double regulator system: the rates are averaged out by the mechanism, which drives the blued gold hour and minute hands of the white stretched-lacquer sub dial. To make things just a bit more complicated, the two flying balances and their escapements are identical mirror images, right down to the position of the stud holders pinning their balance springs.more pictures in press section
Icon of the Legacy Machines, the LM2 has not just one but two bespoke 11mm balance wheels flying above the movement and dials.
The advantage of using a planetary differential is that the two balances beat at their natural rate, with the differential supplying the average of the two completely independent frequencies. This provides a rate with fewer variations.
Superlative hand finishing throughout, respecting 19th century style: polished internal bevel angles highlighting handcraft, Geneva waves and hand-made engravings.
Legacy Machines celebrate complications from past masters, and complications don’t come much more intriguing than connecting two regulators with a differential to drive one time indication. Nor do past masters come more “masterful” than Abraham-Louis Breguet (1747-1823), Ferdinand Berthoud (1727-1807) and Antide Janvier (1751-1835), three men united by their inventive genius and their experimentations with dual regulators.
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 with Legacy Machine No.2 and its double “flying” balances.
Legacy Machine n°2 is available in 18 white or red gold and in a limited edition of 18 pieces in platinum 950.
