First launched in 2014, the Legacy Machine 101 series focuses on the essentials of a mechanical wristwatch, contained in one of MB&F’s most elegant Machines with a case diameter of 40mm: the time, the power reserve, and – the real star of the show, the obsession of any watchmaker, the heartbeat of any mechanical watch – the escapement and balance wheel. But in true MB&F fashion, an unconventional, 3-dimensional “flying” balance wheel, which has become the signature of the Legacy Machine collection.

In 2021, the series evolves with three new editions: white gold with purple dial, red gold with dark blue dial and – a rare occurrence at MB&F! – stainless steel, with a light blue dial. The new editions focus even more on the essentials of mechanical watchmaking: the previous larger bezel and “Legacy Machine” engraving on the dial withdraw to highlight the time and power reserve, indicated on slightly larger sub dials, and the flying balance wheel inherits the amazing double hairspring supplied by H. Moser & Cie. Turning the LM101 over reveals the exquisitely hand-finished movement, at the time MB&F’s first caliber conceived in-house with award-winning independent watchmaker Kari Voutilainen.
