ZRC Grands Fonds MN64 Titanium Rubber Automatic Watch Gradient Dial Rubber Strap 41.5 mm

A professional dive watch with a distinctive identity

The ZRC Grands Fonds MN64 Titanium Rubber continues the legacy of the professional dive watches that established ZRC as a benchmark in underwater watchmaking. With its instantly recognizable design, signature 6 o'clock crown and architecture developed for the most extreme environments, this timepiece perfectly combines technical innovation, durability and contemporary style.

A lightweight and durable Grade 5 titanium case

The 41.5 mm monobloc case is crafted from Grade 5 titanium, a material renowned for its exceptional strength-to-weight ratio, corrosion resistance and anti-magnetic properties. The watch also features ZRC's patented deformable caseback, engineered to distribute pressure evenly during deep dives. It is water-resistant to 3,000 metres and individually tested to an impressive 5,100 metres.

A gradient dial designed for maximum legibility

The striking gradient dial is equipped with three-dimensional LUMICAST hour markers, ensuring outstanding readability in all lighting conditions. Large hands and bold indexes reinforce its professional character, while the 5 mm domed sapphire crystal with anti-reflective coating provides exceptional clarity and outstanding resistance to impacts and scratches.

A ceramic bezel featuring the ECS® system

The unidirectional 60-click rotating bezel is fitted with a highly scratch-resistant ceramic insert. It also incorporates ZRC's patented Easy Clean System (ECS®), designed to naturally flush away salt and debris after every dive, maintaining smooth and reliable bezel operation over time.

The ZRC signature: the 6 o'clock crown

One of the defining characteristics of every Grands Fonds model, the crown is positioned at 6 o'clock and protected by the patented Crown Protection System™. Featuring a reverse-thread double-sealed construction, it enhances both the watch's distinctive appearance and its operational security.

A reliable Swiss automatic movement

Powering the MN64 Titanium Rubber is the Swiss-made Sellita SW300-1 automatic movement in its Elaboré grade. Operating at 28,800 vibrations per hour (4 Hz), it delivers an approximate 56-hour power reserve while offering the reliability and precision expected from a professional diving instrument.

An FKM rubber strap built for adventure

Designed for intensive use, the premium FKM rubber strap offers exceptional flexibility, durability and resistance to extreme conditions. Inspired by the design of ZRC's metal bracelet, it is paired with a lightweight titanium pin buckle, ensuring excellent comfort both underwater and during everyday wear.
