MB&F LEGACY MACHINE 101 (Edition 2021)

MB&F updates its LEGACY MACHINE 101, one of the brand’s most compact machines.

Introduced in 2014, the Legacy Machine 101 (LM101) watch features a 40mm diameter case and a hand-wound mechanical movement entirely conceived by MB&F’s in-house engineering team.

In 2021, the LM101 series welcomes technically and aesthetically-upgraded versions in 18k white gold, 18k 5N+red gold and stainless steel. These new watches boast colourful dial plates. In the upgraded edition, the bezel and “Legacy Machine” engraving on the dial have been omitted to highlight the time and power reserve, indicated on slightly larger sub-dials. The signature “flying” balance wheel inherits a double hairspring.

The dial side of LM 101 is dominated by a massive suspended balance wheel. Two pristine-white sub-dials hover just above the fine sunray engraved movement top plate. At the top right, highly legible hours and minutes are displayed by blued-gold hands, while the 45-hour power reserve indicator is displayed in a smaller, but similar sub-dial below.

Below the highly domed sapphire crystal glass that protects the dial, the balance wheel hangs from elegant twin arches. The arches are milled from a solid block of metal and require many hours of hand polishing to achieve their mirror-like lustre.

Its domed display back crystal reveals the exquisitely hand-finished movement. Sensually curved plates and bridges pay homage to the style found in high quality historic pocket watches.

The LM101 movement was designed and constructed in-house by MB&F. The award-winning independent watchmaker Kari Voutilainen took the responsibility of its haute-horlogerie finishing and decoration, including undulating Geneva waves, hand polished bevels, gold chatons and countersunk blued screws.

LM101 was first launched in 18k red or white gold, then in two limited ‘Frost’ editions with frosted finishing (18 and 33 pieces), followed by limited editions of 33 pieces in platinum 950 and 18 pieces in palladium.

The 2021 upgraded versions are available in 18k white gold with a purple dial plate, 18k 5N+ red gold with a royal blue dial plate, and stainless steel with a light blue dial.
