Limited Edition of 12 watches



The destinies of Moinet the astronomer and Leonov the cosmonaut have been brought together in “SpaceWalker” – an exceptional contemporary creation dedicated to Alexey Leonov, a man who was not only the first to walk freely in space but also the initiator of one of the most symbolic gestures in all history – an interstellar handshake with his NASA counterpart in 1975, at the height of the Cold War, which went on to experience an unexpected thaw.

Tourbillon satellite
The timepiece features an outsize tourbillon at 12 o’clock, representing Alexey Leonov’s spaceship on his Voskhod 2 mission. A diamond revolves around the tourbillon, representing Alexey Leonov himself, floating in space outside his spacecraft. The decision to use a diamond was quite deliberate: “Almaz-2” was Leonov’s code name during the mission (his partner was known as “Almaz-1”) – and “almaz” is the Russian word for diamond. The picture would not be complete without an evocation of the vastness of the cosmos – represented by an aventurine background that becomes transparent when exposed to light.

The dial
The SpaceWalker dial is also an all-new creation by Louis Moinet. It makes use of an exclusive, secret graphic composition, depicting an artistic view of the starry heavens in which Leonov drifted at will for 12 minutes and 9 seconds on March 18, 1965. Also visible is a nebula – a collection of interstellar dust and gases, its exceptional colours providing a unique backdrop for the SpaceWalker. This celestial artwork pays discreet homage to another passion of our two pioneers Alexey Leonov and Louis Moinet – both loved to paint. The innovative method used to produce it is a closely-guarded secret.

A timeless timepiece
At 6 o’clock, Louis Moinet’s characteristic “dewdrop” hands indicate the hours and minutes, extending across a sapphire dial offering glimpses of the mechanics of the fine watchmaking movement. The back offers an unobstructed view, with a sapphire crystal revealing SpaceWalker’s highly distinctive bridges.

“I was heading out into the unknown; nobody in the world could tell me what I would find there. I did not have any instructions. It was the very first time. But I knew it had to be done [...]. I slowly climbed out of the hatch and carefully moved away. Gradually, I went further from the spacecraft [...]. The thing that struck me the most was the silence: utter silence such as I had never witnessed on Earth, so fraught and so deep that I could hear the sounds of my own body [...]. There were more stars in the sky than I had expected. The sky was pitch black, yet at the same time it shone like the Sun... The Earth was small, light blue, and so achingly alone – our home, to be defended like a holy relic. The Earth was absolutely round. I believe I never knew what the word ‘round’ meant until I saw Earth from space.”
Alexey Leonov
