legacy machine 101



For a classically sized 40mm wristwatch, Legacy Machine 101 covers a lot of ground. Or to be more precise, LM101 covers a lot of time: over 100 years between inspiration and realisation.

Legacy Machine 101 embodies and accentuates the very essence of what is essential in a wristwatch: the balance wheel, which is responsible for regulating precision; how much power remains in the mainspring, which indicates when it needs to be next wound; and of course, the time.

LM101 has one more very special feature, one that cannot be seen: it houses the very first movement developed entirely in-house by MB&F.

Visually, LM101 is dominated by the monumental suspended balance wheel. Two pristine-white subdials: At the top right, highly legible hours and minutes are displayed by beautiful blued-gold hands , while the 45-hour power reserve indicator is displayed in a smaller, but similar subdial below.

In an apparent feat of magic, the sapphire crystal protecting the dial appears to be invisible; creating the illusion that you can reach out and touch the balance wheel hanging mesmerisingly from elegant twin arches.

Turning over Legacy Machine 101, the display back crystal reveals the exquisitely hand-finished movement. Sensually curved plates and bridges designed by award-winning independent watchmaker Kari Voutilainen pay homage to the style found in high quality historic pocket watches and testify to the respect accorded to historical legitimacy.

Legacy Machine 101 is available in 18k red, white gold or a limited edition in platinum 950 (33 pieces). Two special limited ‘Frost’ editions with frosted finishing are available in 18k yellow gold (18 pieces) and 18k red gold (33 pieces).



With the ‘Frost’ limited editions, the large balance wheel of LM101 now contrasts magnificently against the effervescent backdrop of a frosted gold dial. Additional contrast is provided by Frost's highly polished bezel and lugs, which make the matte surface of the frosted dial really pop.

For many, the word "frost" conjures forth images of breath-condensing cold and bright, early-morning winter sunshine scintillating off frost-covered lawns. That natural frost sparkles vivaciously due to light reflecting off the microscopically uneven ice crystals – exactly like the LM101 Frost sparkles due to light reflecting off its microscopically uneven frosted surface.

Abraham-Louis Breguet is credited with inventing the “frosted” finish in the late 18th and early 19th centuries. At the time, frosting protected dials and movements from oxidation and added subdued vivacity to movement plates. Traditional frosting methods involved dangerous acids which have been largely replaced by the safer method of carefully compressing the surface with a wire brush. This is however a much more difficult process to master and very few artisans today create true frosted finishes: the majority of surfaces that look frosted have in fact been bead blasted, which does not quite have the same visual impact.

LM101 Frost is available in two limited editions: 18 pieces in yellow gold and 33 pieces in red gold.
