HMX Black Badger


‘Performance Art’ illuminated by smouldering rage



Creativity comes from a multitude of sources, but for ‘Black Badger’ founder James Thompson the fount of his creativity was rage – a rebellious fire was lit when he felt brushed aside as a student by what he perceived as an unfair administrative decision. Like MB&F, Thompson is an outsider doing his utmost to buck the system.


And he is fighting his creative corner with the most unlikely of weapons: luminescent material. Thompson mills three-dimensional objects from solid light!


More than a decade on from a perceived injustice, Thompson's rage smoulders on in the form of vividly glowing lume. As he recounts, "It wasn't that I had tried and failed, it was being brushed aside like crumbs on a table. Here we are 12 years later and I'm still angry about it!"


For the Performance Art collection, Thompson has reinterpreted one MB&F Machine: HMX, first launched in 2015 for MB&F’s 10th Anniversary


For HMX Black Badger, Thompson redesigned the "rocker cover" of HMX's Engine, visible under the supercar-like sapphire crystal cover, milled from his signature solid blocks of brightly coloured, high-efficiency lume.


While the colours – Radar Green, Phantom Blue, and Purple Reign – are eye-catching by day, it's when the sun goes down that they really come out to party. The long-lasting glow emitted by the high efficiency lume irradiates the HMX Engine compartment in an ethereal bath of light.


HMX displays bi-directional jumping hours and trailing minutes. Light streaming through the transparent Engine cover both illuminates the top of HMX's Engine by day, and by night the brightly glowing lume provides its own colourful backlight to the time display.



HMX Black Badger is a limited edition of 3 x 18 pieces in grade 5 titanium and stainless steel, with lume in Radar Green, Phantom Blue, or Purple Reign.



Black Badger lume and the composition and energy of light



While most watch enthusiasts are likely to be familiar with lume in the form of Super-LumiNova-enhanced hands and markers, that substance is quite different to the luminous material exclusive to Black Badger. While Super-LumiNova is a liquid that is applied to surfaces and dries, Black Badger's lume comes in solid blocks that are milled by hand or machine into the desired shape. Not only is Black Badger's lume extremely efficient at storing and releasing light, being solid means that there is usually more of it, so that it shines brighter for longer.


"White" light, which includes sunlight, is actually composed of red, green, and blue wavelengths of light. There are also other wavelengths of light outside our visible range, including infrared, a red that is just beyond visible, and ultraviolet, which is a blue that is just beyond visible. These different colours or frequencies of light contain varying levels of energy, with red/infrared at the lower end of the energy scale and blue/ultraviolet at the upper end.


When charging luminous material from white light, most of the energy comes from the more energetic ultraviolet end of the spectrum. But as ultraviolet is only a small fraction of white light source emitted by most torches and sunlight, only a small fraction of the power of the light source will actually charge the lume. An ultraviolet light, on the other hand, will charge lume much more quickly because it is all high-energy light, so more energy is absorbed by the lume more quickly.


This effect means that while normal white light sources will more easily charge the Black Badger Radar Green and Phantom Blue colours, an ultraviolet light is needed to charge the Purple Reign lume because it absorbs more energy.
