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.
