ZRC, founded in 1904 by Edmond Zuccolo and Joseph Rochet, has constantly innovated by imagining bracelets and straps and then dive watches. In 1909, when it was established in Geneva, it was issued with No.52 when the Geneva Trade and Companies Register was created. In 1917, the firm won the highly-coveted Prix de l’Industrie Nouvelle de Genève for having developed the first-ever extendable metal bracelet and became world leader for producing it. In 1958, with Louis Brunet at the helm, the firm embarked on its ZRC Grands Fonds adventure and become official supplier of the French Navy. 50 years after the first Grands fonds 300, Georges Brunet, at the head of the family business (great-grandson of Joseph Rochet), launch the re-issue of this iconic model. The ZRC GF300 is reborn.

ZRC has a strong expertise in the field of the strains studies linked to the programmed deformation of materials, which guarantees the manufacture of waterproof watches at very great depth (5100M) without resorting to a helium valve or the presence of gel in the case: In addition, it also reduces the thickness of the case making the watch more comfortable to wear. This is also why up to date famous special units such as the GIGN, the Mine Clearance Group & the Hubert Commandos still wear ZRC watches.
