zrc Grands Fonds Bronze – Limited Edition No. 1/170 An iconic model based on historic specifications from the French Navy, specifically designed for mine-clearing divers and elite units such as the Hubert Commando. The zrc Grands Fonds is a true tool watch, originally designed to meet the demands of professional diving. I am offering here the bronze version, which is particularly sought-after, from its limited series, with an exceptional serial number: number 1 out of 170 pieces. This is the very first model in this series, making it a rare and coveted piece. The bronze case has developed a natural patina over time, giving the watch a unique character. Rotating bezel in good condition. Crystal in very good condition, scratch-free. The faint visible marks come from the black-backed display dial and not from the crystal. Automatic watch, water-resistant to 300 meters / 1,000 ft, anti-magnetic, true to the DNA of professional diving watches. ZRC leather strap in good condition. Works perfectly. Sold with its original purchase receipt. No box or screwdriver included. Authentic watch with a strong technical and historical identity, ideal for diving enthusiasts, watch aficionados, or collectors seeking a rare piece, particularly in this bronze No. 1 configuration from the Grands Fonds series. I am available for any further information.
