MB&F Legacy Machine No.1 (LM1)

With brand new three-dimensional timepiece: Legacy Machine No.1 (LM1), Swiss luxury watch maker MB&F pays tribute to the great innovators of traditional watch making. This futuristic horological machine features a monumental central balance; superlatively finished movement; completely independent dual time zones; unique vertical power reserve indicator and elegant annular case.

In fidelity to high-quality 19th century pocket watches, LM1 features a sedately oscillating (2.5 Hz), large diameter balance with traditional Breguet overcoil suspended from majestic twin arches; its enigmatic regulating mechanism in full view, but without apparent connection to the movement. Both the hours and the minutes on each of the two sub dials can be set completely independently of each other – dual time zone complications usually do not allow independent adjustment of the minutes – their domed dials further reinforcing visual references to the golden age of watchmaking (1780-1850). Looking like a miniature sextant, a world-first vertical power reserve indicator keeps track of available power while providing a visual three-dimensional counterpoint to the graceful arches supporting the balance.

Legacy Machine No.1’s transcendental in-house movement bears testimony to the enormous talent of its creators. Jean-François Mojon and his team at Chronode (Best Watchmaker Prize at the 2010 Grand Prix d’Horlogerie de Genève) met the considerable challenge of developing the calibre for LM1 from a blank sheet, while acclaimed independent watchmaker Kari Voutilainen took responsibility for the aesthetic design and for strictly ensuring the utmost respect for tradition and finish. Immaculate Geneva waves, highly-polished gold chatons and bridges with impeccably executed bevels following deliberate internal angles (which cannot be finished by machine) showcase the movement’s absolutely peerless fine-finishing. The movement of Legacy Machine No.1 proudly bears the names of both its creators, and is the first calibre other than Voutilainen’s own to bear his name.

 

LM1’s ingenious three-dimensional movement was specifically developed for MB&F from Maximilian Büsser’s sketches by Jean-François Mojon and his team at Chronode in Le Locle, Switzerland. The balance wheel and spring are at the very heart of any mechanical watch movement and are responsible for regulating timekeeping accuracy. Büsser has long been fascinated by the large slowly oscillating – 18,000 bph compared with the 28,800 bph common today – balance wheels of antique pocket watches, so it was no surprise this was his starting point from which to let his fertile imagination roam free. He has re-interpreted tradition by relocating the balance wheel from its more usual position hidden at the back of the movement to not just the top of the movement but majestically floating above the movement, even floating above the dials.

While the location of Legacy Machine No.1’s regulating organ may be considered avant-garde, ‘tradition’ is upheld by the large 14mm diameter balance wheel with regulating screws specifically developed for MB&F, balance spring with Breguet overcoil and mobile stud holder.

Another very special feature of the LM1 movement is the ability to set the two time zones completely independently. The vast majority of dual time zone movements only allow the hours to be independently adjusted, a rare few offer setting to the half hour. Legacy Machine No.1 allows both hours and minutes of each dial to be set to whatever time the user wishes.

The world’s first vertical power reserve indicator on LM1 is driven by an ultra-flat differential with ceramic bearings allowing for a slimmer complication and a more robust and longer-wearing mechanism.

The rate keeping of the twin dials is controlled by the same regulator (balance and escapement) so that once set, the two times stay perfectly synchronised with each other. Both the hours and minutes on both dials can be set to any time desired via their respective crowns.

Complementing the three-dimensionality of the balance floating in space, the dual white dials with their bright blue gold hands float above the top of the movement. The dials are gently domed with a translucent, high-gloss lustre created using a laque tendue process in which multiple layers of lacquer are applied and heated, causing them to stretch over the surface of the dials.

To ensure aesthetic purity of the dials and their traditional Roman numerals, a sophisticated fixation underneath negates the necessity of visually obtrusive used screws. A fine golden perimeter circumscribing each dial elegantly reinforces their timeless classicism.

Acclaimed master watchmaker Kari Voutilainen assumed responsibility for ensuring the historical accuracy of the style and finishing of the Legacy Machine No.1 movement.

A finely engraved sun-ray pattern on top of the movement plate (dial side) subtly catches the eye at certain angles without distracting attention from the twin white dials, floating balance or vertical power. But it is in the style and finish of the bridges and plates visible through the display on the back of the movement where Kari Voutilainen has excelled in providing exquisite historical fidelity in both the shape of elegantly curved bridges and the traditionally wide space between the bridges and between the perimeter of the bridges and the case.

On the back of the movement, over-sized ruby jewels set in highly-polished countersunk gold chatons provide striking visual counterpoints to the Geneva waves traversing the sensually curved bridges. While providing historical links with the large jewels seen in high-grade antique pocket watch movements, the ruby bearings have a practical application in reducing wear/increasing longevity by accommodating large diameter pinions and holding more lubricating oil.
