For Bell & Ross, each detail has a purpose, and legibility is one if its guiding principles since the very beginning. With that in mind, the brand has explored the concept of luminescence and designed timepieces known for their unfaltering legibility day and night. LUM has become one of the brand’s true signatures.Building on from the success of its predecessors - the BR 05 SKELETON was adorning a grey dial in 2019 and a blue version was released in 2020 -, the skeleton movement of the BR 05 now attires itself in black with a hint of green. Super-Luminova® treatment facilitates reading during the day and at nighttime. Thus, the metal applique skeletonized indices and hands are filled with green-emitting Super-LumiNova® C5. This type was specifically chosen for its pale yet strong green daytime color and its exceptional brightness qualities. When the night falls, the pale green background turns fluorescent green and will allow a persistent reading during the night hours.
