ZRC GRANDS FONDS 300 HERITAGE brown dial steel bracelet 38 mm

A modern tribute to the 1964 Grands Fonds S2

With the Heritage CHESNUT, ZRC pays tribute to one of the most iconic watches in its history. Inspired by the Grands Fonds S2 introduced in 1964, this model faithfully revives the vintage aesthetics of the original while incorporating the technical innovations that define the French manufacture today. Combining timeless proportions with true professional diving capabilities, it perfectly embodies ZRC's distinctive Sport Vintage philosophy.

A unique glacé brown gradient dial

The highlight of this edition is its striking glacé brown gradient dial, whose subtle fumé effect evolves beautifully as it catches the light. Newly designed applied hour markers, inspired by ZRC's "Electron" models of the 1970s, add depth and sophistication, while the finely crafted luminescent hands and precise minute track ensure exceptional legibility. The warm tones of the dial give the watch an elegant personality that transitions effortlessly from everyday wear to more formal occasions.

An iconic 39 mm stainless steel case

The 39 mm monobloc case is crafted from anti-magnetic 316L stainless steel and preserves the compact proportions of the original Heritage model. Its patented deformable caseback is engineered to better distribute pressure during deep dives, reinforcing the watch's outstanding durability. Positioned at 6 o'clock, the signature screw-down crown is equipped with ZRC's patented Crown Protection System™, featuring a reverse-thread mechanism and double sealing system to maximise both safety and water resistance.

A bezel designed for underwater precision

The unidirectional 60-click rotating bezel allows precise dive-time measurement while maintaining the authentic appearance of the historic Grands Fonds models. Its aluminium insert reinforces the vintage character of the watch while remaining highly functional for everyday and professional use.

A reliable Swiss automatic movement

The Heritage CHESNUT is powered by the Swiss-made Sellita SW200-1 automatic movement in its Elaboré grade. Operating at 28,800 vibrations per hour (4 Hz), it provides approximately 41 hours of power reserve and delivers the reliability, precision and robustness expected from a true mechanical tool watch.

An elegant Milanese steel bracelet

This version is fitted with a finely woven Milanese bracelet crafted from anti-magnetic 304L stainless steel. Developed specifically by ZRC, it combines exceptional comfort, flexibility and durability while enhancing the refined vintage character of the watch. Its sliding clasp allows precise wrist adjustment for optimal comfort in every situation.

A versatile dive watch for every adventure

Water-resistant to 300 metres and pressure-tested to 1,000 metres, the Heritage CHESNUT remains a genuine professional diving watch despite its refined appearance. Blending vintage-inspired design, patented engineering and Swiss mechanical expertise, it is equally at home beneath the surface or as an elegant everyday companion.
