Launched in 2008 the Horological Machine 2 was as much UFO as it was a kinetic wrist sculpture.

Staying true to Maximilian Büsser’s unique interpretation of independent watchmaking, the HM2 is the world’s first mechanical engine to offer an instantaneous jumping hour, concentric retrograde minutes and date, bi-hemisphere moon phase with automatic winding movement.

Shortly after Max Büsser contacted Alain Silberstein, the genius designer/watchmaker best known for his playful and colorful designs to reinterpret the HM2 in the “Silberstein way” (and this is years before Silberstein became the designer so many brands wanted to work with).

The result was the Horological Machine 2.2 made in only 8 pieces, where Silberstein didn’t just add his touches of color but completely redesigned the watch.

While the twin porthole dials are still the focal point – though now with the jumping hours in an aperture for the first time – the watch’s personality has changed completely - gone is the science-fiction look of the original. Silberstein says that his aim was for Horological Machine N°2.2 to combine the pure geometry of the Bauhaus with the user-friendliness of the miniature box cameras of the 1940s.

The jumping hours, on the right-hand dial, are presented in an aperture, which is framed by the concentric retrograde minutes. The left-hand dial presents the retrograde date and the moon phase.

The present example of the Horological Machine 2.2 is the rarest one as it is a unique piece with chocolate colored PVD coating (whereas the limited edition pieces were black), explaining its nickname "Chocolate Box" and giving the watch incredible appeal.

Please note that MB&F generously offers a complementary servicing of the watch to the winning bidder within a period of 6 months after the sale.
