MOONMACHINE 2

MB&F + Sarpaneva

 

As strange as it might sound, moonlight doesn’t exist. It is an illusion, and even the word “moonlight” is misleading. The moon gives off no light of its own, it only reflects light from the sun. In effect, moonlight is sunlight, projected onto Earth via the moon.

If there’s one person who can be relied upon to thoroughly grasp this concept, it’s Stepan Sarpaneva, the independent Finnish watchmaker whose work has become synonymous with the moonphase display. Little wonder, then, that the second collaboration between MB&F and Stepan Sarpaneva has resulted in a horological creation that occupies the same elusive space as moonlight, somewhere between illusion and reality. The MB&F MoonMachine 2 brings us the world’s first projected moonphase display.

MoonMachine 2 comes housed in the case of Horological Machine Nº8, the first MB&F creation to possess two design icons of the Horological Machine collection: the battle-axe rotor, and the heads-up time display first seen in Horological Machine Nº5. The stripped-down case construction of HM8 emphasised the illusory nature of the projected hours and minutes, and MoonMachine 2 uses the same mechanism to highlight the visual impact of a moon disc appearing in a space too small to fully contain it.

The projection is accomplished via an optical prism, which refracts the hours, minutes and moon discs in their flat positions to appear as if they are perpendicular to the engine. The prism is cut to magnify the hours and minutes by 20 percent for greater readability, but not for the moonphase display, which is at risk of distortion if magnified. The case of MoonMachine 2 is 0.5mm thicker than that of HM8, to accommodate the additional moon disc, and has a pusher on the side for quick adjustment of the moonphase display.

 

The battle-axe rotor of HM8 has been transformed into an openworked radial web of titanium, echoing the design vocabulary of Stepan Sarpaneva’s best-known work. The sapphire crystal pane framing the top of the MoonMachine 2 engine has been metallised in a similar pattern and draws focus to the variable sheen of the brushed titanium rotor as it rotates.

 

There are three instances of the immediately recognisable Sarpaneva moon in MoonMachine 2, its piercing eyes and pointed features based on Stepan Sarpaneva’s own face. Two of the Sarpaneva moons are mounted on the moon disc, taking it in turns to cycle under a Korona ring — another Sarpaneva design hallmark — to indicate the phase of the moon. The third is mounted on the winding rotor. Each moon is made of gold and finished by hand, which is incredibly challenging at their size. The two small moons on the moon disc measure 4.5mm in diameter and 0.35mm in thickness, while the rotor moon is 8.5mm wide and 0.45mm thick. The hand-finishing process is extremely delicate and the failure rate is very high, meaning that each completed moon will be the result of multiple work sequences.

 

A Korona-framed gold plaque commemorating the collaboration between Stepan Sarpaneva and MB&F is affixed on the sapphire crystal pane, adjacent to the crown. According to MB&F founder Maximilian Büsser: “We would never have done MoonMachine 2 on our own, and Stepan would never have done it on his own. But that’s what I love about Performance Art pieces — the chance to expand the MB&F universe in unexpected ways.”

 

Stepan Sarpaneva’s take on the project is illuminatingly personal. “Max and I have a very long friendship, and there is a lot of honesty between us. He pushes me to do better and gives me the most challenging projects. This time the challenge was to augment HM8, which is not easy. But it’s fun, and that’s why I say yes to any project with Max.”

 

MoonMachine 2 is available in three limited editions of 12 — one in full titanium with white gold moons and a light-blue sky, one in blackened titanium with white gold moons and a dark-blue sky, and one in red gold and titanium with red gold moons and an anthracite sky.

MOONMACHINE 2 IN DETAIL

 

ABOUT HOROLOGICAL MACHINE Nº8 AND THE HM8 ENGINE

 

First launched in 2016 as the adrenaline-laced “Can-Am”, Horological Machine N°8 is an evolution of the heads-up time display that MB&F debuted five years ago in the HM5 “On the Road Again” and subsequently refined in the 2015 HMX.

The HM8 engine is a compact, in-house developed movement built on a Girard-Perregaux base, with a jumping hour disc and a running minutes disc. Optical prisms fixed over the discs at specific points capture the time, refracting and magnifying the numerals so they can be read on a vertical plane. Horological Machine N°8 is completely pared down in terms of exterior cladding, not just to emulate the bare-all aesthetic of Can-Am racecars, but also to allow as much light as possible to flood the prisms and maximise the clarity of display.

Additional references to the source material include the slender titanium roll bars flanking the crown, sweeping forwards to anchor the time display cylinder. Motoring enthusiasts will immediately recognise the “oil sumps” visible through the sapphire crystal panes on the underside of HM8 — these are functional as well as decorative, providing access to the pivots of the hour and minute discs for tribological maintenance.

 

 

CHALLENGES OF THE MOONPHASE IN MOONMACHINE 2

 

The gold moons of MoonMachine 2 are the smallest ever created by Stepan Sarpaneva, whose timepieces have, on average, gold moons that are 10mm in diameter and 0.5mm in thickness. In comparison, MoonMachine 2 has one moon that is 8.5mm in diameter and 0.45mm in thickness, and two exceptionally small moons that are 4.5mm wide and 0.35mm thick.

 

The smallest gold moons are first stamped to a thickness of 0.55mm, and then reduced by hand-turning on a lathe to bring their height down until just under 0.4mm. They are then manually ground down with a stone tool until they are 0.35mm at their thickest point, then matt blasted to create an even finish. At their thinnest point, around the eyes, the moons can be as little as 0.07mm thick, almost like a gold foil, and the slightest pressure will cause the soft gold to perforate and the moon will have to be discarded.

 

The 4.5mm-wide moons are at the very limits of what can be worked on by hand — any smaller and the features of the moon’s face will no longer be clearly visible. As it is, they are hardly discernible by touch, even by the experienced fingertips of Stepan Sarpaneva and his team. These near-impossible dimensions are necessitated by the constraints of the MoonMachine 2 case and the tolerances needed to fit under the optical prism while providing adequate clearance for the hour and minute discs.

 

On average, eight moons out of every 10 are eventually discarded for not meeting the high standards set by Sarpaneva and MB&F. Furthermore, the small moons come in pairs, since there are two on each moon disc, so they have to be perfectly matched as well as perfectly finished.

 

MB&F AND STEPAN SARPANEVA

In 2012, when the first MoonMachine was presented, the MB&F-Sarpaneva connection was the first time that a piece of MB&F Performance Art had been produced in conjunction with a watchmaker, and it continues to hold a special place in the MB&F pantheon.

 

The evolution of this partnership is represented by the advancement between the first MoonMachine, which was based on the HM3 Frog, and MoonMachine 2. Although they both utilise the rotor and moonphase display as locus points for incorporating the Sarpaneva contribution, MoonMachine 2 takes this seemingly straightforward addition and gives it an exponential bump by turning it into a world premiere — the first ever projected moonphase display.

 

MB&F founder Maximilian Büsser and Sarpaneva began talking of a sequel to MoonMachine not too long after its release, when HM5 was released and Stepan suggested that a moonphase indication could go between the hours and minutes of the first Horological Machine to use the optical prism display. It wasn’t until HM8, however, four years after MoonMachine, that this became more than a suggestion and laid the foundations for MoonMachine 2.

 

ABOUT STEPAN SARPANEVA

 

Stepan Sarpaneva was born in 1970 to a Finnish family with a long heritage of craftmanship. Son of jewellery designer Pentti Sarpaneva, Stepan was brought up to be a talented designer and craftsman.

 

Sarpaneva first graduated from the Finnish School of Watchmaking and then moved to Switzerland to further his studies at WOSTEP (Watchmakers of Switzerland Training and Educational Program). In 1994, he began work for several prestigious watch companies including Piaget, Parmigiani, Vianney Halter and Christophe Claret. During those 10 years in Switzerland, Sarpaneva specialised in the crafting of complicated timepieces.

 

Perfectionism, enthusiasm and an infinite passion for watchmaking inspired Sarpaneva to create watches of his own. In 2003 he founded his own company in Helsinki, Finland where he individually handcrafts each watch at the workshop.

 

Stepan Sarpaneva first got to know Maximilian Büsser in 1999 and their first collaboration was the 2012 MoonMachine, built on the framework of the HM3 Frog. Sarpaneva is the first watchmaker to collaborate on an MB&F Performance Art piece, and his work is characterised by his love of the cosmos. Common features include the moonphase complication and design motifs such as stars and the Korona, Sarpaneva’s own stylised representation of the Sun’s plasma halo
