Description

The Legacy Machine 101 (LM101) series was first launched in 2014. As suggested by its “101” name, it focuses on the essentials of a mechanical wristwatch, contained in one of MB&F’s most compact Machines with a case diameter of 40mm.

In 2021, the LM101 series evolves with technically and aesthetically-upgraded versions distinguished by colourful dial plates, including a stainless steel version. Focusing further on the essentials, the bezel and “Legacy Machine” engraving on the dial withdraw to highlight the time and power reserve, indicated on slightly larger subdials; and the star of the show, the signature “flying” balance wheel, inherits a double hairspring.

Turning over the LM101, the display back crystal – domed to reduce the thickness of the caseband and, visually, the height of the watch – reveals the exquisitely hand-finished movement. Sensually curved plates and bridges pay homage to the style found in high quality historic pocket watches and testify to the respect accorded to historical legitimacy.

With its undulating Geneva waves, hand polished bevels, gold chatons and countersunk blued screws, the beauty of LM101’s movement doesn't just stay faithful to a bygone era. In 2014 it also heralded the dawn of a new epoch as it was the first MB&F calibre to be entirely conceived and designed in-house. Indeed, while award-winning independent watchmaker Kari Voutilainen took responsibility for the movement's fine finishing specifications and fidelity to the horological past, its architecture and construction are 100% pure MB&F.
