The Horolum collection reflects the spirit of Bell & Ross instrument watches. The case, designed in a contemporary style, incorporates the “circle within a square,” an iconic Bell & Ross shape, reminiscent of the silhouette of an aircraft cockpit clock. The microblasted steel case and dial give the watch a monobloc effect. Its sandwich dial is made up of two overlapping metal plates. The characteristics specific to the “Horo” models have the common objective of unfailing readability.
