Bell & Ross launched its LUM line in 2017 with the BR03‐92 HOROLUM line. The brand has since unveiled other new models in the same category including the BR03‐94 HOROLUM and BR03‐92 NIGHTLUM and, more recently, the BR03‐92 FULL LUM. The suffix ‘LUM’ in their name means ‘lumière’ —light— and refers to one of the fundamental qualities of Bell & Ross watches, which are celebrated for their unfaltering legibility. These models, with micro‐blasted steel or matte ceramic cases, have exceptional display qualities thanks to the application of superluminova C3.
