The case of the Bentley GMT B04S Cabon Body is composed of tiny carbon fibres woven into several hundred layers placed at a 45-degree angle between each successive layer, and then bonded by heat-set resin. This matt black envelope protects the B04 calibre entirely developed and manufactured by Breitling. This chronograph also provides a second timezone function, coordinated with a list of reference cities appearing on the rotating pinion bezel. The carbon bezel is knurled across its entire surface, marking out this 250-piece limited edition as a member of the Breitling for Bentley family.
