MB&F unveils a latest version of the HM8 Mark 2

Inspired by iconic supercars, now with blue body panels similar to car paints.


“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.”  Maximilian Büsser, Founder and Creative Director – MB&F.


MB&F – short for Maximilian Büsser & Friends – has recently unveiled the latest version of the HM8 Mark 2, now featuring blue CarbonMacrolon® body panels. HM is short for Horological Machines. It was first launched in 2023 in two versions: a version featuring white CarbonMacrolon® body panels, and a version with green CarbonMacrolon® body panels, the latter in a limited edition of 33 pieces. This latest version features a “glossy sapphire-blue body panels recalling car paints, both technically and aesthetically.”

Max Büsser and MB&F’s love for cars led to the automotive inspired Horological Machines: HM5 (2012), HMX (2015) and HM8 (2016). In 2023, a decade after the HM5, MB&F introduced its first supercar inspired HM8 Mark 2. The HM8 Mark 2,“with its distinctive “double bubble” sapphire crystal, finds inspiration in the design of some of the most iconic supercars.” 

– Reputed watch designer Eric Giroud, owner of Through the Looking Glass, is responsible for the HM8 Mark 2’s product design. He is among the many “Friends” of MB&F, having collaborated with them on other projects.

– The HM8 Mark 2’s “deep, iridescent sapphire blue is obtained from metallic pigments of mineral origin, the same as those found in metallic car paint.”

– The HM8 Mark 2 is “powered by a unique combination of mechanical and optical engineering.” 


Its functions are hours and minutes. It features “bi-directional jumping hours and trailing minutes, displayed by dual reflective sapphire crystal prisms with integrated magnifying lens.”
