Mark in Paris introduces the MB&F Horological Machine No.6 'Space Pirate,' hailing it as his favorite in the HM series. This post provides an in-depth look at the watch's design and technical specifications, inviting the community to explore its innovative features through detailed descriptions and visuals.
Horological Machine No.6 (HM6) ‘Space Pirate’ has been designed to operate in the hostile environment of space: the space on your wrist.
In each of the four corners of HM6's biomorphic case is a 360° sphere, capped top and bottom by transparent sapphire crystal domes. Up forward, two semi-spherical indications rotate vertically, displaying hours and minutes. Back aft, driven through multiplying gearing by the automatic winding rotor, twin spherical turbines spin horizontally, automatically regulating the winding system in case of excessive speed to reduce stress and wear.
The transparent central dome houses a 60-second flying tourbillon, the precision regulator of HM6's Engine. This flying tourbillon can be protected from UV radiation, which speeds up oxidation of lubricating oils, by a retractable shield operated by a crown on the left side of the case.
While the transparent cupola on top of HM6 Space Pirate offers a tantalising glimpse into the sophisticated Engine below, the sapphire crystal display portal on the back reveals more of the 475 finely finished components making up the highly complex movement, which required over three years of development. Also visible through the display back is part of the winding mechanism and the platinum 950 winding battle-axe rotor.
While Horological Machine No.6's gentle curves and bulging "eyes" may give it the appearance of a friendly extra-terrestrial life form, the strength of its exoskeleton is formidable thanks to the aeronautic grade Ti-6Al-4V titanium case. And a titanium brace runs around the central circumference of the hull, reinforcing the structure and supporting the lugs.
HM6 ‘Space Pirate’ is a limited edition of 50 pieces in Ti-6Al-4V titanium. There will only be 100 HM6 movements made in total.





and I'm sure the time is easier to read on this watch than on many "classic" dials ;)
and it pushes some boundaries in terms of design, technology and construction. It must be hand charmer - sorry: wrist charmer! - and a really cool object on the wrist. It reminds me a bit on this: Best, Magnus
You spoted a right image Magnus. Indeed this new HM is bringing something very different from the previous models and it is, to me, very interesting and appealing. Cheers, Mark
The most impressive MB&F in my opinion. I'm imagining taking this timepiece to my local watchmaker to be serviced .... would elicit quite a response. Hope to be lucky enough to see one of these in the metal some day. Thanks for posting. Darren
I love the shape, the tourbillon etc ... Certainly successful for a happy few :) Cheers, Mark
Impressive on the wrist. Would love to see a wrist shot to see how it looks. There will be some lucky owners out there. Cheers Steve
