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, MB&F revealed the supercar-inspired HM8 Mark 2 in 2023.

After a successful introduction of two editions in 2023 – with white or green body panels, the latter limited to 33 pieces – the HM8 Mark 2 comes back with a new 2024 limited edition featuring glossy sapphire blue bodywork, again limited to 33 pieces. Thanks to their metallic pigments and a translucid material, the blue body panels recall luxurious car paints, both technically and aesthetically.

Automobile-Inspired Body Panels

Automobile-Inspired Body Panels

Not only did the design codes of the HM8 Mark 2 find their inspiration in the automobile world, but the construction did too. The HM8 Mark 2 is built from an independent water-resistant chassis to which the body panels of the watch are added.



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.



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.



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.

The HM8 Mark 2 finds inspiration in some of the most iconic supercars – not only in terms of design, with the distinctive “double bubble” shape of the sapphire crystal, but also in terms of actual case construction. The HM8 Mark 2 is built from an independent water-resistant chassis to which the body panels of the watch are added, while previous models like the HMX and HM8 favoured a monobloc construction.
