MB&F updates the HM8 with a new Mark 2, now in two editions – White and Green.

Press Release information with commentary in italics.

New: MB&F HM8 Mark 2

The retail price for both the White and Green editions is set at CHF 68,000 before taxes. The Green edition is a limited edition of 33 pieces.


The HM8 series started with the HM8 release edition in 2016 as also known as Can-Am. This novelty is a revision to the release model, and is monikered Mark 2. While the launch model was based on the cars in the American Can Am Challenge Cup, the Mark 2 is modelled after the Porsche 918 Sypder, and the Zagato double bubble for the sapphire case. The movement in the HM8 remains to be based on the Girard-Perregaux caliber.

While the base HM8 design remains unchanged, the new Mark 2 watch looks totally different – thanks to eht ehood design and what MB&F calls the coachworks. The dual hump on the top is a reminder of the famous Zagato double dome design. And the material chosen for this coachwork in a choice of either a pure white or British racing green. Both look equally cool.

We await our turn to photograph this novelty, and will bring you more later.

Release information

MB&F’s connection to cars runs deep, starting in 2012 with the HM5, followed by the HMX in 2015, and the HM8 in 2016. Each of these iterations is linked by its instantly recognizable speedometer-style display on the side of the case that recalls the daring and futuristic design of the 1970s.

A decade after the first automotive-inspired MB&F Machines, get ready for the silk-covered reveal of the latest HM8 Mark 2, the most technologically evolved model to date.


To fully understand MB&F’s link to the car world, we need to step back in time to 1985 for a moment. As children, we all have dreams, some of them come true, others get abandoned along the way, and some are so part of who we are that they end up happening despite us. This was the case with MB&F’s Founder Maximilian Büsser, who spent the majority of his childhood dreaming about becoming a car designer. He was so smitten with the idea that from the age of 4 to 18, cars were the only thing he would sketch and draw. When his classmates started discovering other areas of interest, his heart remained steadfastly loyal to the automobile with its aerodynamic lines and sleek forms. 

Just before graduating from high school, he learned that the world-famous ArtCenter College of Design from Pasadena, was opening a campus in Europe, and not just in Europe, but in La Tour-de-Peilz, a stone’s throw from his childhood home. Could this be a sign? He could hardly contain his excitement until he discovered that the school fees were CHF 50,000, a huge amount of money today, and an even more colossal sum back in 1985. 

Knowing how much he loved cars, his parents said they would find a way – but Maximilian knew that it would be too much for them. So as everyone keeps telling him he would make a very good engineer as he was so good at maths, he signed up for the Swiss Federal Institute of Technology Lausanne (EPFL), and that could have been the end of the story, only it wasn’t. 

I lost my way, I lost my marbles, and ended up in the watchmaking industry,” he shares with a smile. “So, when I decided to tackle car design in a timepiece, this was humungous for me. It was everything I had ever dreamed of.


He found inspiration in a crazy design by Amida, called the Amida Digitrend, a watch that was unveiled in 1976, just before the company went bankrupt. Working on a similar idea, MB&F employed a sapphire prism that would allow the jumping hours and sweeping minutes to be indicated vertically, when they were actually flat as a pancake on top of the movement. The time was indicated in a window that resembled an old-style speedometer on the front of the case that could also be easily viewed while driving, no less. Unlike the Amida, with its discs next to each other, the MB&F HM design features discs that are one on top of the other, maximising the size of the digits and therefore the legibility.

The idea didn’t end there, as the mission was to make the numerals look almost digital or electronic. This was achieved using sapphire disks that were coated with a black metallization, leaving the numerals clear. Super-LumiNova® was then added underneath the sapphire disc, so that the luminescence would be completely flat, not bulbous as it appears when it is applied to the dial. It is interesting to note that the numerals had to be created back-to-front as they get reversed in the prism. 

This system came to life in the HM5 with opening and closing slats that allowed the light into the movement to charge the luminescence. These slats were inspired by Marcello Gandini’s design for the Bertone Lamborghini Miura with its louvers on the rear window that gave the car its futuristic aesthetic.

These slats were dropped in the following model – the HMX – in favour of a sapphire crystal cover that gave a partial view on the engine beneath. This piece was inspired by another Italian coach builder – Touring Superleggera – and was equipped with miniature oil caps that could be unscrewed and filled with watchmaking oils 

Next came the HM8 ‘Can-Am’ with a sapphire crystal that also allowed a view on the spinning rotor. It was this movement, based on a Girard-Perregaux calibre, that is also providing the base for the brand-new HM8 Mark 2. The HM8 took its design cues from Can-Am cars (hence the nickname) from the famous Canadian American Racing Championship. The cars’ unusual design and distinctive roll bars became the inspiration for the watch’s two titanium roll bars. 

The HM8 Mark 2, on the other hand, finds inspiration in different sources, such as the iconic Porsche 918 Spyder for the shape of the body, and the Zagato double bubble for the sapphire crystal. 


Not only did the design codes of these timepieces find their inspiration in the automobile world, but the construction did too. That engineering degree was not wasted on Maximilian after all! The HM5 and HM8 Mark 2 are built from an independent water-resistant chassis to which the body panels of the watch are added, while the HMX and HM8 favoured a monobloc construction. 

For the new HM8 Mark 2, this coachwork comes in a choice of white or British racing green CarbonMacrolon® that has a matt finish on the top and a high polish on the sides. The white version is paired with a green CVD rotor and light green minute markers, while the British racing green version comes with a red gold rotor and balance wheel and turquoise minute markers and is limited to 33 pieces. 


Developed specifically for MB&F, CarbonMacrolon® is a composite material composed of a polymer matrix injected with carbon nanotubes, which add strength and rigidity. Carbon nanotubes offer superior tensile strength and stiffness than traditional carbon fibre reinforcing. MB&F’s CarbonMacrolon® is a solid material that is hard and can be coloured, polished, bead-blasted, lacquered, satin-finished… 

In addition to all these attributes, it weighs eight times less than steel, making it extremely versatile and interesting from both a technical and design point of view.


Like any super- or hyper-car, a lot of the technology inside the HM8 Mark 2 is not visually obvious, starting with the titanium chassis, which is extremely complicated to mill. Even in stainless steel, it would have been extremely complex to make, but the hardness of this alloy really put MB&F’s technicians to the test. 

The same is true of the CarbonMacrolon® body panels, which due to the small production quantities, could only be milled from a block, adding another layer of complexity to the watch’s coachwork. 

A long line of MB&F timepieces has pushed the limits of what is physically possible in terms of sapphire crystal production, and the HM8 Mark 2 is no exception. The creation of this double-curved sapphire has reached a complexity that is 30 to 40 times more expensive than a dome sapphire. Only one supplier agreed to take on the challenge. During the many hours required to produce each sapphire crystal, the risk of breakage is incredibly high – and if it is going to break, it is always at the very last moment, much to the utter desperation of all concerned. Once safely completed and fitted into the timepiece, however, it is just as robust as the sapphire crystal on any sports watch. 

And last, but not least, the battle axe rotor that powers the movement is incredibly complex to make as one of the 22-carat gold blades is only two-tenths of a millimetre thick. It cannot possibly be machined so it had to be stamped, with the engraving already incorporated into the stamp.  


Not under the hood, but equally hidden, is a brand-new type of crown that has a sort of “double de-clutch” system, to coin an automobile term. It works by pushing the crown in and turning it three-quarters of a turn to release it. This has the advantage of gaining space and providing additional security to the system, which is a genuine advantage for a sports watch.  

The HM8 Mark 2 takes everything that MB&F fans have loved in this automotive series over the last 10+ years and has made it more technical, more legible, sexier and easier to wear. But more than that, it is a reminder that, wherever you are in life, it is never too late to follow your dreams.
