The Ace Jewelers x Cedric Bellon collaboration is based on the brand-new CB01 GMT. This watch was designed and produced specifically to be as sustainable as possible. The case is smartly designed to reduce material need and machining time. It is created using 100% recycled PuReSteel from ThyssenKrupp. All components have a raw, industrial finish, eliminating the need for environmentally damaging processes such as galvanic baths, paints, inks, varnishes or glues. The self-winding movement is sourced from unused stock. The result is a sustainability score of 87.59% [full report available via DropBox], or about 2.09 times more sustainable than a comparably priced series watch.
