Product Details
The matte black ceramics immediately set the tone, evoking the technical features and clean lines of stealth vessels or explorers' equipment. In 2019 Bell & Ross regularly offered special editions in this compelling material. This year, the BR 03 Diver Black Matte Ceramic has been discreetly redesigned to provide significant improvements in readability and power.
The two-part construction of the bezel is a distinctive feature of the BR 03 Diver Black Matte Ceramic. The bezel itself and its insert are both ceramics, the insert benefits from the same improvements to resistance and readability as the models in steel. Enthusiasts will also immediately notice the enlarged type on the graduated scale. Like the new BR 03 Diver in steel, the new BR 03 Diver Black Matte Ceramic benefits from the improved design of the hands, the enlarged indices, and the new rubber strap.
