Equipped with a manufacture movement, the BR-X5 Green Lum pushes the limits of creativity and innovation thanks to the use of LM3D, a luminescent composite. The architecture of the BR-X5's multi-component case in this assembly alternates between multiple layers of LM3D and grade 2 microblasted black titanium with a DLC (diamond-like carbon) finish. Cut from a block of grade 2 titanium with a DLC finish, the container which houses the mechanism is inserted between two shields in LM3D, a photoluminescent composite material made from quartz fibres and which glows bright green.
