VIDEO: The MB&F Legacy Machine N°2 Explained

Two years ago, we introduced you to the latest creation from MB&F, the Legacy Machine Two. The watch features two over-sized balance wheels "flying" over a multi-layer lacquer dial and a differential wheel at 6 o'clock. The result is an absolutely unbelievable display of ingenuity, and one of the coolest "traditional" watches we've seen in a long time. Today, we are happy to present you with this original video that explains the MB&F Legacy Machine N°2 in all its glory.

The LM2 is not the first watch to feature two independent escapements. Some of the greatest watchmakers (ever) built watches with this architecture, including Breguet, Berthoud, and Janvier, though those watches were in fact resonance watches and featured two individual movements. In the 1930s, the very best students at the watchmaking school in Le Sentier built a small handful of pocket watches that featured two escapements averaged by a planetary differential. Just 10 of these were made, and one may been seen here:

Then, in 1996, independent watchmaker Philippe Dufour built the first wristwatch with this layout in the Duality. Only nine pieces were made, and it can be said that this is the watch that inspired MB&F to build the Legacy Machine Number Two.

The first time that MB&F founder Max Büsser saw the Duality, he thought right there, "how beautiful would this look on the front of a dial?"

But before he could put two balance wheels on the front of a dial, he had to put one. And the result was the Legacy Machine Number One, which featured two independent dials run off of a single escapement. The LM1 was a huge critical and commercial success, winning two awards at the 2012 GPHG.   

Legacy Machine Two is very much the descendent of the LM1, in that it uses the same 44mm traditional case. The dials also look very much the same and the movement designers and finishers remain the same – Jean-Francois Mojon, and Kari Voutilainen, respectively. 

Here, the planetary differential that sits at 6 o'clock essentially takes the average of the two independent balance wheels, which beat freely of each other and freely of any would-be resonance. 

You can see a better diagram of the gear train right here: 

It should be noted that the large outer dial of the LM2 is actual the underside of the movement's baseplate, and though the star of the dial side is certainly the two floating balance wheels and oversized differential, the finish here is excellent. 

And, while the front of the LM2 is remarkable on its own, the watch really becomes special once you turn it over and see what Mojon and Voutilainen have done together. This movement is drop. dead. gorgeous. 

Another look: 

The Legacy Machine Two is also surprisingly wearable. It remains 44mm in diameter but has gained a bit in height due to the dual balance wheels. Still, it is a very wearable watch considering all that it has going on, including the giant domed crystal.   

After my first hands-on experience with the LM2 I was left absolutely taken aback.  I had thought the LM1 would remain my favorite between the two due to its increased functionality (dual timezone) and larger singular balance wheel, giving the dial a very clean look. I was wrong – the LM2 is actually the watch I prefer and the dual balance wheels beating away next to each other is just remarkable, as you can see in the video above. 

The LM2 is available in rose gold (pictured) and white gold, both at $156,000, and a limited edition of 18 pieces in platinum with a blue dial (also seen above) at $190,000. You can read more about the amazing MB&F Legacy Machine Two right here.
