The very first HM3 Frog from 2010 already presented a significant advance in its time, with the twin domes in sapphire crystal over the indications of time. Not only did the curvature of the domed “eyes” have to be exactly right, the thickness of the crystal was strictly controlled throughout so as not to distort the time display.
In FrogX, the two sapphire domes are fused to the upper case body, itself also entirely in sapphire crystal, creating an additional level of difficulty. Machining and polishing each case of HM3 FrogX requires weeks of intensive and meticulous work, a number that would be multiplied greatly if not for MB&F’s 15 years of experience in boundary-pushing sapphire crystal design since 2005.
Like the vivid colours that nature endows upon its feistiest creatures, the FrogX is brightly coloured by day with its matching oversized rotor and gasket, and is luminous at night thanks to the Super-LumiNova on the fluorescent segments under the rotor and on the time display domes.
Those looking at the winding and setting crown of HM3 FrogX, expecting to see the usual battle-axe insignia, will be slightly baffled to find a smooth, highly polished disc (although exceptionally observant individuals may notice a slight irregularity in its reflection of light). At just the right angle, with just the right kind of directional light and just the right receiving surface, the final secret of the fully exposed FrogX is revealed. A secret signal, created by sculpting the metal crown at microscopic levels to allow it to reflect light in highly specific ways, is the key to unlocking the MB&F battle-axe.
To create this secret battle-axe signal, MB&F worked with light-sculpting techniques pioneered by Rayform, a Swiss company whose technology has various applications, from design to anti-counterfeiting measures.
After decades conforming to the rules of corporate watchmaking, Max Büsser broke the chains and started a rebellion in 2005; a rebellion called MB&F - Maximilian Büsser & Friends.
MB&F is an artistic concept laboratory based around a simple idea: to assemble collectives of independant watchmaking professionals to develop radical watches - Horological or Legacy Machines. By nurturing teams of talented individuals, harnessing their passion and creativity and crediting each person's essential role, MB&F uses their synergy to become much greater than the sum of its parts. Respecting tradition, but never constrained by it, MB&F reinterprets traditional, high-quality watchmaking into three-dimensional kinetic sculptures.
Horological Machine N°3 was first presented in 2009, and in its six years of production became MB&F’s most popular model. Before FrogX, the case and movement architecture gave rise to nearly 20 variations: the HM3 Starcruisers and Sidewinders, HM3 ReBel, JWLRYMACHINES, various HM3 Frogs, MoonMachines, and the MegaWind variants. Apart from its straightforward success as an MB&F creation, HM3 (and particularly HM3 Frog) is also the emotional touchstone of the MB&F Tribe, the global community of owners and aficionados that constitute an essential part of the universe of Maximilian Büsser & Friends.
