In 2011, Maximilian Büsser and his friends (MB & F) cut us the breath with its admirable Legacy Machine. A watch of avant-garde making an incredible tribute to the watchmakers of the 18th century. Two years later, MB & F continuing the development of this collection with the arrival of the Machine 2 Legacy. Always developed in partnership with Jean-François Mojon and Kari Voutilainen. You don’t change a winning team. Certainly, the wonder of the first time disappeared… But the magic remains intact. Max and his friends have the gift to make us dream and we dive back to childhood with watches completely non-standard and mysterious…
The collection of Legacy Machines re-interpret remarkably inventions signed by major watchmakers of history. If the Legacy Machine N ° 2 appears contemporary, with its two pendulums hanging from four high arches over the dial, there is nothing paradoxical. Do not be mistaken, this is a watch inscribed in the story line, long of 250 years, drawn by three of the greatest watchmakers who have ever lived: Abraham-Louis Breguet (1747-1823), Ferdinand Berthoud (1727-1807) and Antide Janvier (1751-1835). Explanations…
Watch legends of the 18th century have in common not only their creative genius, but also the fact that they have built clocks and watches to two pendulums. Oscillating height, double rocker highlighted in the LM2 is inspired by the double historical regulators and their tribute. These mechanisms are among the rarest in watchmaking. Even more rare are the models that regulate a single train of gears – more often found two independent movements. In the Legacy Machine N ° 2, the average of the balances markets is established by a differential.
Under a dome domed Sapphire, the dial of the Legacy Machine No. 2, whose base is in fact the top plate delicately decorated movement, is a perfect illustration of the symmetry. From top to bottom: the balance between the small dial in white tight lacquer accented with hands in blued gold, at 12 hours, and the great differential elevated at 6 o’clock. From left to right: mirroring the two floating hangers and their exhausts which extends to the position of the door-peaks in the spiral.
Although the two balance wheels which oscillate levitating attract and hold the eye of the beholder (difficult to detach), it is the great planetary differential enhanced on the dial which is the true heart of the Legacy Machine N ° 2. “Create a complex high-precision mechanism is the feat” highlights the brand in its release. The rarity of multiple regulators connected by a single differential watches evidenced. Its role is threefold: provide power to each of the regulators, record rates of each balance and transmit the average markets to the Cog to ultimately intervene in the time display.
Like that of the LM1, the movement of the Legacy Machine N ° 2 was developed, under the directive of MB & F, by the watchmaker Jean – François Mojon (best watchmaker to the Grand Prix D’horlogerie de Genève 2010) and his team of Chronode. The aesthetic was placed under the responsibility of the renowned independent watchmaker Kari Voutilainen. He defined the hand finishes in ensuring their compliance with the exception of the 19th century watches movements. The refined finishes are without equal: Côtes de Genève impeccable, kittens in gold, polished bevel mirror and angles deliberately reentrant, impossible to complete machine. Spirit of transparency of MB & F requires, the names of the responsible men of the movement are carved by hand on the back.
Even today, despite design assisted by computer (CAD) software and very high-precision CNC machines, it takes expertise to assemble and adjust complex mechanical movements by providing a high-performance timekeeping in different positions. As the either flat or vertically – focused on the top, bottom, left or right – the components of the movement, in particular the balance, are slightly affected. In turn, they interfere on the precision of the time.
In the 18th century, while production techniques involved more tolerance and oils were of low quality, it was almost impossible to adjust a movement with high precision can we expect today. It is therefore not surprising that the greatest watchmakers of the time have tested a variety of mechanisms to improve Chronometry.
While Ferdinand Berthoud (1727-1807) work its two mechanical regulators, Abraham – Louis Breguet (1747-1823) and Antide Janvier (1751-1835) created double regulator watches using the resonance to the average of the two pendulums markets. It should be noted that most of the watches of the genre, especially those who used the resonance, had only two not regulators but also two complete movements.
These watchmakers geniuses realized that a limited number of clocks and watches to double regulator (some each), which indicates that they doubted that the result is at the height of the effort. Nearly a hundred years later in the 1930s, some students among the best in the school of watchmaking in the Vallée de Joux realized pocket watches to dual controller with a planetary differential to make the average of the balances markets. They were generally two copies – one for them, one for the school. It is estimated that there are ten in the world.
After seeing one of these pocket watches, Philippe Dufour, independent watchmaker in the Vallée de Joux, was inspired to create his Duality. Launched in 1996, is the first wristwatch equipped with two pendulums connected by a differential known. Subsequently, there were very few examples. “The advantage of a planetary differential” recalls mark, “is that the two pendulums fighting at their natural pace, the differential averaging two completely independent frequencies. In other modes of coupling, the first rocker produced a slowdown or one acceleration of the other, which leads to slight pressure in the system’.
If the Legacy Machine N ° 2 may appear as a traditional round watch, its three-dimensional architecture delights the eye to several points of view. What appears at first glance as the main dial is actually the top plate of the movement. It has been finely decorated and plated (or blued for the Platinum model). The Legacy Machine name is engraved on the hand under the differential. The dial of the hours and minutes is slightly raised from the baseline. Its fine outline highlights or the purity of the tense white lacquer surface obtained by applying multiple layers, successively heated so they spread perfectly. White contrasts with the bright blue of the needles in gold, slightly curved to the convex shape of the dial. To enhance the aesthetic purity of this dial punctuated by traditional Roman numerals, placed mounting below replaces screws which might impair the aesthetics.
Planetary differential emerges proudly from the surface, supported by a polished bridge set with both arms bent, mirror of three large rubies. This complex mechanism is the key element of the double control system. It appreciated all the more it is placed just above the movement. Oscillating pendulums created custom wheels are suspended in height compared to the dial and the differential. Both regulators, spiral Breguet and four adjustment screws, are reflections of the other and they react inversely to the different forces. The distance between the wheels was carefully calculated to avoid the phenomenon of resonance that would interfere negatively on the regulation.
