All about the ZRC Geneve HETERIUM GF421618 - 41.5mm - 1,000m

ZRC Grands Fonds – Perfect symbiosis of tradition and technical excellence

On the steel band

The ZRC Grands Fonds combines classic design with the highest functional reliability and a distinctive modern character. As a contemporary interpretation of the legendary Grands Fonds 300®, this model embodies the essence of a professional diving watch. Equipped with a rubber strap, this variant not only brings robustness and durability but also a high level of wearing comfort – both underwater and in everyday life.

Elegance and functionality in maritime style

The gradient dial, which gently transitions from deep navy blue to an intense black, evokes the mysterious depths of the ocean. Combined with the satin-finished stainless steel case and the integrated rubber strap, it creates a watch that meets the highest standards both visually and technically. The unidirectional rotating ceramic bezel ensures optimal control during dives, while the innovative ECS® system (patented under N°1462496) allows for automatic flushing and reliably removes deposits such as salt crystals.

Bracelet and clasp

The watch strap is made of high-quality FKM rubber, which is known not only for its comfort but also for its remarkable durability. It has been specifically designed to perfectly match the design of the metal bracelet, ensuring an elegant yet functional aesthetic. The flexibility and soft texture of the rubber ensure that the strap remains comfortable even during prolonged wear, while also meeting high demands for stability. The strap is available in a variety of colors, making it ideal for adapting to the personal preferences of the wearer.

The steel clasp ensures a secure hold with a classic, one-piece tongue lock that provides easy handling and reliable security. This design not only offers the necessary stability but also contributes to the overall elegant appearance of the watch.

Crystal clear visibility in any environment

To ensure that the time remains easily readable even in demanding situations, the ZRC Grands Fonds is equipped with a domed, 3 mm thick sapphire crystal. The anti-reflective coating provides maximum clarity and prevents distracting reflections – whether on land or at great depths.

Outstanding water resistance for extreme conditions

This diving watch was designed for depths of up to 1000 meters and tested under extreme conditions – with a durability of up to 1500 meters. Thanks to its precise construction and high-quality materials, it is a reliable companion for anyone who expects absolute safety in challenging environments.

Precise Swiss movement for the highest demands

Inside the ZRC Grands Fonds, the proven Sellita SW300-1 "Elaboré" works, a high-quality Swiss automatic movement with a precision of +5 seconds per day and a maximum amplitude deviation of 0 to 10 seconds per day. With an impressive power reserve of 56 hours, the watch remains reliable even when not worn for several days.

Conclusion – A watch for explorers and perfectionists

The ZRC Grands Fonds is not just a diving watch, but a true precision instrument that masterfully combines tradition and innovation. With its unique combination of high-quality materials, innovative safety mechanisms, and a stylish, functional design, it is aimed at all those who seek adventure – both underwater and in daily life.
