MB&F Legacy Machine N°1 Final Edition

MB&F Legacy Machine N°1 Final Edition

Completing an MB&F series is a major strategic decision and is central to the belief in continual exploration and development that is held by everyone at MB&F. Only by ending production of existing pieces are Maximilian Büsser and his team able to move on to future challenges while keeping the creative spark and momentum that comes with a compact organisation.

The Legacy Machine N°1 Final Edition makes the last outing of the series in steel, with a dark chocolate face, wearing the white lacquer dials, suspended balance and gracefully arched power reserve indication in their well-known configuration. A new balance bridge, cambered and tapered in the style MB&F introduced to audiences in the Legacy Machine 101, is the one departure from the original design and acknowledges the evolution and maturation of the Legacy Machine collection.


The dark chocolate-toned face of the LM1 Final Edition is not the first instance of this color appearing in an MB&F creation. Wherever and whenever it occurs in the MB&F collections, the deep brown hue signals a special occasion, a reason to break out the treats, and the Legacy Machine N°1 Final Edition is no exception to this rule. The launch of the last LM1 may be a bittersweet celebration for some.  MB&F founder Maximilian Büsser pinpoints it at 85% dark chocolate since the edition is limited to 18 pieces.


The balance bridge of the Legacy Machine N°1 Final Edition is new in the LM1 series. It follows the code premiered in the Legacy Machine 101, which has since been propagated in the LM2 series via its titanium incarnation, and in the Legacy Machine Perpetual.

The original LM1 came about as a reanimation of 19th-century design, particularly in association with technological advances. The open-worked balance bridge, with its sharply defined angles, echoed the girders and crossbeams of industrial structures showcased at the famous World’s Fairs of that era.


As the Legacy Machine collection grew into its own, its focus naturally shifted away from specific historical design references. A smoothly curved balance bridge with an elliptical cross section, milled from a single steel block and demonstrative of a high level of machining sophistication, was designed to fit the smaller proportions of the Legacy Machine 101.


Thereafter, it made its second appearance in the 2015 Legacy Machine Perpetual and again in the 2017 LM2 Titanium. The lithe, mirror polished arms of the redesigned balance bridge set it apart from the satin-finished bridge of the original LM1, seemingly a small detail, but one that magnifies the impact of the floating balance. The polished balance bridge clearly stands out against the sunray-finished base, cinematically emphasising the aerial poise and height of the balance.


Legacy Machine No.1 is available in 18k red gold, 18k white gold, a limited edition of 33 pieces in platinum, a limited edition of 13 pieces for the M.A.D.Gallery Dubai in titanium and the final edition limited to 18 pieces in stainless steel. The LM1 was also the base for two Performance Art editions with artists Xia Hang and Alain Silberstein.
