Having used Super-LumiNova for the numerals, indices, hands and dial on previous pieces, Bell & Ross is going even further with the BR-X5 GREEN LUM and its innovative composite material: LM3D.

For the structure of this new version of the BR-X5, lightness comes first on the multi-component case, which alternates LM3D and grade 2 micro-blasted black DLC titanium in a multi-layer assembly. Cut from a block of DLC-coated grade 2 titanium, the case housing the mechanism is inserted between two shields made from a photoluminescent composite material, LM3D, made of quartz fibres that diffuse a powerful green luminescence.

In the dark, the entire case glows, highlighting the dial's indications: hours, minutes, seconds, date and power reserve.

Beyond its watchmaking function, with this innovation, the new 500-piece limited BR-X5 GREEN LUM series achieves the rank of one-of-a-kind conceptual art object.
