MB&F – Legacy Machine Perpetual EVO Zirconium Limited Edition
Over the past 15 years, MB&F creations have transported their wearers to destinations that exist only on maps of the imagination: from star-cruisers to deep-sea jellyfish, Maximilian Büsser’s Machines are the mechanical cartographers of the multiverse.
But the greatest journey has yet to be undertaken, and true progress is marked by evolution. Presenting Legacy Machine Perpetual EVO: with this new Machine, you are the navigator; the map is your life. On this journey, you’ll never have to leave your watch behind.

When Stephen McDonnell set out to redesign the perpetual calendar for MB&F, he proposed a system that rethought the entire mechanical basis of the complication. The LM Perpetual uses a “mechanical processor” consisting of a series of superimposed disks. This revolutionary processor takes the default number of days in the month at 28 — because, logically, all months have at least 28 days — and then adds the extra days as required by each individual month. This ensures that each month has exactly the right number of days, and removes the possibility of the date jumping incorrectly. An inbuilt safety feature disconnects the quickset pushers during the date changeover, so that even if the pushers are accidentally actuated whilst the date is changing, there is no risk of damage to the movement.

Reinforcing the dynamism and durability of the LM Perpetual EVO is a new dial plate colour — a shade of orange that is as bright as it is difficult to achieve. Although dark shades of PVD and CVD coating have been used for years in watchmaking, with colours towards the cooler end of the visible light spectrum becoming more common recently, warmer hues such as yellow, orange and red have always remained unattainable. A combination of technical innovations in the areas of coating material and coating technique allows the LM Perpetual EVO to don this atomic shade, bringing the next level of horological heat to your wrist. Two other dial-plate colours, black and blue are also available, with each of the three shades produced in a limited series of 15 pieces – celebrating the brand’s 15th anniversary.
In design, in technique, in spirit, Legacy Machine Perpetual EVO is an evolution of your story with MB&F.
The LM Perpetual EVO is not a watch for sports. It is a watch for life.
A MATTER OF MATERIALS
The LM Perpetual EVO comes in a case of zirconium, a metal rarely used in watchmaking due to the extreme requirements involved in machining this high-risk material. When zirconium is finely divided into a powder, as might happen when it is being worked into different forms by industrial tools, it is known to combust. During conventional machining processes, when metallic particles are constantly being created and dispersed through the environment, zirconium has proved extremely dangerous. The creation of zirconium metal parts has to be conducted under controlled, secure conditions.

The LM Perpetual EVO introduces a new paradigm for MB&F — the use of zirconium is not in support of the journey of imagination initiated by the watch concept; it is the means by which LM Perpetual EVO will keep pace with whatever journey you choose to embark upon.
CALENDRIC COMPUTATION
Conventional perpetual calendars are generally modules comprising the complication, which is fitted on top of an existing movement. The calendar indications are synchronised by a long lever running across the top of the complication and passing through the centre. As the date changes, this long lever transmits information to the appropriate components and mechanisms by moving backwards and forwards. This traditional system, while beautiful in its interplay of levers and components, is also extremely unwieldy, restricting movement construction in several key ways that would make something like Legacy Machine Perpetual a mechanical impossibility.

In the traditional system, perpetual calendars assume that, by default, all months have 31 days. At the end of months with fewer than 31 days, the mechanism quickly skips through the superfluous dates before arriving at the 1st of the new month. Any manipulation or adjustment of the date during changeover can result in damage to the mechanism, requiring expensive repairs by the manufacturer. The dates can also jump or skip during changeover, negating the whole point of the perpetual calendar in the first place, which is not requiring adjustment for years. Or decades.

Legacy Machine Perpetual uses a “mechanical processor” consisting of a series of superimposed disks. This revolutionary processor takes the default number of days in the month at 28 – because, logically, all months have at least 28 days – and then adds the extra days as required by each individual month. This ensures that each month has exactly the right number of days. There is no "skipping over" redundant days, so there is no possibility of the date jumping incorrectly.
Using a planetary cam, the mechanical processor also enables quick-setting of the year so that it displays correctly in the four-year leap year cycle, whereas traditional perpetual calendar mechanisms require the user to scroll through up to 47 months to arrive at the right month and year.

In 2015, Legacy Machine Perpetual premiered the world's longest balance wheel pinion, connecting the hovering balance to the escapement on the back of the engine. This technical feat has since been showcased elsewhere in the MB&F collection, namely the Legacy Machine Split Escapement.

ORANGE ALERT
Finding a new shade of PVD or CVD treatment may seem at first to be a purely aesthetic endeavour that requires little in the way of technical expertise or innovation, but that could not be further from the truth. Colours that are a result of PVD or CVD (physical or chemical vapour deposition), are not simply applications of ordinary pigments. PVD/CVD coatings were originally reserved for utilitarian purposes, providing a thin layer of protective material for reasons of tribology, or to extend the longevity of mechanical parts.

The LM Perpetual EVO is the first timepiece to exhibit a bright orange shade of CVD coating, in line with the game-changing approach to watchmaking at MB&F.
