Inspired by the Can-Am racing series, Horological Machine N° 8 is the tenth collaboration between MB&F founder Maximillian Büsser and independent designer Eric Giroud. The Canadian-American Challenge Cup (Can-Am) was a sports car racing series running from 1966 to 1987.
The intricate case of Horological Machine N° 8 has a curvaceous yet angular form and features dual optical prisms vertically displaying bi-directional jumping hours and minutes, while the distinctive battle-axe winding rotor is visible on top. But these are two titanium bars across the front of the watch that attract attention due to their resemblance to a racing car’s roll bars. Just like most car engines have an oil sump underneath, the back of the case of HM8 reveals dual “oil sumps”, which however are not just pretty design elements, but are fully functional oil caps that the watchmaker unscrews to oil the jewelled bearings of the indication discs.
The nearly invisible sapphire crystal engine cover reveals HM8’s engine, a Girard-Perregaux base movement that has a 42-hour power reserve. The open centre of the battle-axe rotor enables appreciation of the circular wave finish on the movement, while the hours and minute indication discs are visible day and night in the corners.
The bi-directional jumping hour and trailing minute displays are materialised by overlapping discs completely covered in Super-LumiNova and reflected from the discs 90° by two sapphire crystal prisms. The HM8 automatic movement displays bi-directional jumping hours and trailing minutes, powered by a 22k gold winding rotor.
The HM8 Can-Am is available in two versions: 18K white gold/titanium and 18K red gold/titanium and comes with hand-stitched alligator strap in marine blue (white gold case) and dark brown (red gold case) with folding buckle in matching case material.
