- GRANDS FONDS 300 by ZRC
A world first! For the re-issue of The Grands Fonds, ZRC has developed and patented a functional solution: The ECS™. The “Easy Clean System” is a unique system for cleaning the inside of the bezel by circulating fresh water that dilutes and evacuates the sea salt. A technical solution to the problem of all divers: the salt crystallises in the gaps between the bezel and case, thus impeding its rotation.
