MB&F HMX- A 10th Anniversary Horological Machine

MB&F celebrates its 10th anniversary in 2015, and to mark this occasion, the Swiss horological concept presents HMX, a true Horological Machine offered in an unprecedented price.

The tag line for MB&F's 10th anniversary is “A creative adult is a child who survived”, a reference to a child's sense of wonder and awe that usually fades under the onslaught of the everyday realities of reaching adulthood. As a child, MB&F founder Maximilian Büsser dreamt of becoming a car designer and his sketchbooks were full of drawings of the supercars of his imagination. The automobile-inspired HMX is proof positive that the child in Büsser survived.
HMX displays bi-directional jumping hours and trailing minutes. Rotating discs on top of the movement feature mirror image numerals. These are reflected 90° and magnified by two sapphire crystal optical prisms that "project" the time onto the front vertical display. Light streaming through the transparent engine cover both illuminates the top of HMX's engine and backlights the time display for high legibility.
Also visible through the sapphire crystal engine cover are supercar-inspired dual "rocker covers" on top of the movement, each featuring shiny chrome oil filler caps. These oil caps are not just pretty design elements, but are fully functional oil caps that the watchmaker unscrews to oil the jewelled bearings for the indication discs. An automatic winding mechanical movement provides HMX with power, its "fuel" topped up by the 22K gold rotor visible through the display back. HMX is a limited edition of 4 x 20 pieces in grade 5 titanium and stainless steel, available in Lotus Black, British Racing Green, Ferrari Red and Bugatti Blue.
The vertical hour and minute display on HMX are derived from circular discs rotating flat on top of the movement. Each of the two discs (one for the bi-directional jumping hours, one for the minutes) is printed with mirror image numerals that are reflected and magnified by two triangular-shaped optical prisms, reflecting the time onto the vertical forward facing display. A gap between the two prisms allows light to flood onto the Engine from the front as well as the top, and the light coming in from the top backlights the indications, making them even more legible.

The sapphire prisms are wedge-shaped with the angles precisely calculated to ensure that light is reflected from the horizontal indications to the vertical rather than refracted (bent). A convex lens at the front provides the magnification. Sapphire crystal is much more difficult to work to optical precision than glass and it took considerable development and meticulous care in production to create crystals that reflected and bent light without the slightest distortion.

The influences of a number of supercars can be seen in HMX's design cues. In particular, the distinctive Superleggera style of renowned Italian coachbuilder Carrozzeria Touring – creators of automobiles like Alfa Romeo’s Disco Volante – resonates throughout the “coachwork” of the Machine.

The four colours of HMX are all carefully selected motor racing colours: Lotus black, for one of the most successful teams in the history of motor racing; British racing green, which should originally have been red, white and blue, but those colours were already taken by the USA; Bugatti blue, apparently inspired by the colour on Mrs. Bugatti's Gauloise cigarette packets; and Ferrari red, which is the Italian official motor sport colour.
