Famed for their wacky designs, incredible engineering and fresh concepts, MB&F has become one of the most influential independent watchmakers in the world. Of course, like most MB&F timepieces, the HM2 is no ordinary watch, instead a truly wonderful celebration of horological passion and wonder. Taking inspiration from as far away from the world of horology as possible, the HM2 was inspired by “the space platforms of 20th century science fiction novels.” Following such a unique source of inspiration, the HM2’s case had to be made with over 100 parts alone, of which make its flying buttresses, bolted portholes and sliding crown guard. With such a unique construction to deal with, Patrick Lété was tasked with making sure the HM2’s automatic movement would fit harmoniously inside of it, and what a job he did. On the caseback we can see the HM2’s 22k gold ‘battle-axe’ automatic winding rotor, which you may recognise from the M.A.D. 1. On the display side, the HM2 boasts a bi-hemisphere moonphase indicator at 9 o’clock and a jump hour/retrograde mechanism at 3 o’clock which combine with the construction to achieve an incredibly unique visual effect as the entire watch looks as though it came straight out of a science fiction film. Made of sapphire and 18kt red gold, the example we have here was limited to just 18 pieces and serves as a wonderful celebration of MB&F’s desire to create watches unlike anyone else in the market.

Skeletonized and boasting a bi-hemisphere moonphase indicator at 9 o’clock and a jump hour/retrograde mechanism at 3 o’clock, the HM2 provides full view of its incredible architecture and internal workings as its unique construction had to be worked around to fit it with a movement that would do what was required.


While its unique sapphire and 18kt red gold construction is indeed unique, the HM2's proportions mean that it is more wearable than one might think.

Watch is in near-mint condition. There is some light surface oxidation on the caseback visible. Watch appears almost unworn.

Please Note: Due to CITES considerations, if the watch is to be shipped outside of the USA, the exotic skin strap will have to be removed.

Our Perspective

An intensely unique watch, like so many of MB&F's designs, the HM2 pushed boundaries in a way that was completely new for 2008. However, with its sapphire and red gold construction, the example we have here is easily the most incredible variant produced.
