Grade 5 Titanium World Record Grands Fonds MN64 Watch GF4226121118WR

The Watch

ZRC presents an extraordinary timepiece: the Grands Fonds MN64 Titane World Record, purpose-built for extreme-challenge enthusiasts and deep-sea diving aficionados. Crafted from Grade 5 titanium, it delivers remarkable lightness without compromising durability. The tonneau-shaped case features a combination of matte and polished finishes, giving the watch a look that is both modern and timeless. At 41.50 mm in diameter, it is perfectly sized for the male wrist, reinforcing its bold masculine character. Swiss-made to the strictest Helvetic standards, this watch is engineered to deliver precision and robustness in every condition. It pays tribute to the exceptional record set by Stéphane Tourreau, Brand Ambassador, who completed a dive to -145m in 2026 - an achievement celebrated by this limited edition of just 50 pieces. With its screw-down case back and monobloc construction, it promises unmatched water resistance and lasting durability.

The Dial

The dial of the ZRC Grands Fonds MN64 is a masterpiece of legibility and style. Offered in a captivating gradient Caribbean blue, it evokes the depth and vastness of the ocean. Finished with a smoked effect, it provides optimal contrast with luminescent indices and hands produced via 3D-printed SLN-X1 material. These use LUMICAST technology to ensure exceptional readability in the most challenging low-light conditions - particularly during dives. Arabic numerals enhanced with SuperLuminova further boost the dial's visibility and practicality for deep-water diving. A domed sapphire crystal with anti-reflective coating protects the dial while delivering perfect clarity in any lighting condition.

The Movement

At the heart of this iconic timepiece beats a Sellita SW 300-1 movement - a high-precision Swiss automatic caliber. Operating at a frequency of 28,800 vph (4 Hz), it delivers accurate, reliable timekeeping. The movement features a rotor that ensures efficient self-winding in harmony with the wearer's wrist motion. With a 56-hour power reserve, this watch stays running long after you've taken it off. Hours, minutes, and seconds are clearly displayed, perfectly embodying the analog soul of this high-performance timepiece.

The Bracelet

The strap of the ZRC Grands Fonds MN64 is crafted from blue FKM rubber - a supple, durable material with outstanding water resistance. This choice of material gives the watch a sporty edge while delivering maximum comfort, essential for long dives and aquatic activities. Thanks to its exceptional resistance to wear and UV rays, the strap retains its shape and vibrant color over time. The lug design flows seamlessly into the case, ensuring a cohesive aesthetic. Secured by an ardillon buckle, the strap provides a firm, reliable fit that stays in place through even the most demanding activities.

Water Resistance

Built for the deepest ocean depths, the ZRC Grands Fonds MN64 Titane is rated to 300 ATM (3,000 meters), making it the ultimate tool watch for professional diving. Featuring a screw-down crown and a secured monobloc case back, it remains completely reliable even in the most extreme marine environments. This level of water resistance, combined with innovations like the CPS™ (Crown Protection System), ensures water never reaches the watch's delicate inner components - preserving both its structural integrity and performance. ZRC doesn't just make a watch; it engineers a precision instrument designed to push the boundaries of maritime exploration.
