MB&F welcomes a new version, the LM2 Ti, to its Legacy Machine N°2 line of exceptional horological machines. Dressed in a Titanium Ti-6Al-4V alloy case, this new model boasts a vivid green dial.
The rounded profiles of Legacy Machine N°2 Ti’s majestically arching balance wheel bridges impart a softer aesthetic than the original LM2 models. Its highly polished and redesigned bezel makes the case a full one millimeter slimmer than those of its predecessors. Ti-6Al-4V (grade 5), the high-tech titanium alloy used in aerospace and medical applications, offers a perfect blend of strength and lightness, ensuring that LM2 Ti sits seductively and comfortably on the wrist. When that spectacular PE-CVD-treated green dial catches the light from alternating angles, it comes alive with constantly changing iridescent sheens and hues of green and blue.
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. Oscillating on high, the exalted double balance wheels of LM2 were inspired by, and pay homage to, 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, which is actually the top plate of the exquisitely finished movement, 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. The differential has three roles: 1. Transferring power to each of the regulators; 2. Receiving the individual timing rates from each balance; and 3.Transmitting the average rate of the two regulators to the gear train, where it finally manifests itself as the displayed time.
The movement of Legacy Machine No. 2 was developed to MB&F’s specifications by award-winning watchmaker Jean-François Mojon and his team at Chronode. Acclaimed independent watchmaker Kari Voutilainen ensured that the movement’s aesthetic style was consistent with high-quality traditional timepieces of the 19th century and for specifying the superlative hand-finishing.
Immaculate Geneva waves, gold chatons, mirror-polished bevels and bridges designed with deliberate internal bevelled angles (which cannot be finished by machine) 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 are hand engraved on the back.
Legacy Machine No.2 was launched in 2013 in 18k red gold, 18k white gold and a limited edition of 18 pieces in platinum 950. It was redesigned in 2017 for a limited edition of 18 pieces in titanium.
Legacy Machine N°2 Ti is a limited edition of 18 pieces in a titanium Ti-6Al-4V alloy case.
