The BR-X5 Green Lum pushes the limits of creativity and innovation thanks to the use of LM3D, a luminescent composite.  Luminescent materials have been used since the 1930s to cover the indexes and numerals on timepieces designed for professionals, starting with the military. 

The architecture of the BR-X5’s multi-component case alternates between multiple layers of LM3D and grade 2 micro blasted 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 fibers and which glows bright green.

Driving the BR-X5 is the Calibre BR-CAL.323  with 70-hour power reserve running a frequency of 28,000 alt/h. The 28-jewel movement has a variable-inertia balance wheel,  maintaining a chronometer-grade spec via a COSC certification. The movement is equipped with a rapid date correction device.  The Calibre BR-CAL.323 is visible via a sapphire exhibition case back, showcasing a Bell & Ross signed skeletonized oscillating weight.

The BR-X5 comes supported with a 5 year warranty.
