ZRC Grands Fonds MN64 Titane Record du Monde: history, models and owner reviews

 

---

The ZRC Grands Fonds MN64 Titanium World Record is an extreme dive watch created to celebrate a very real sporting achievement: the new CMAS world record in variable weight set by Stéphane Tourreau at -145 metres on June 26, 2026, in Sharm El Sheikh, Egypt. A ZRC ambassador since 2015, the French freediver tested the MN64 Titanium during his preparation, well beyond 120 metres. To accompany and commemorate this performance, ZRC developed a specific version of its Grands Fonds 3000, produced in only 50 pieces. This reference GF4226121118WR is officially priced at CHF 4,290.

What makes this edition especially powerful is that it is not merely an aesthetic variation. The MN64 Titanium World Record tells a real story of the field, pressure, depth and physical preparation. It retains the emblematic architecture of the Grands Fonds — monobloc case, 6 o’clock crown, ECS® system and programmed-deformation caseback — while adding a Caribbean blue gradient dial, 3D LUMICAST indexes and a commemorative dimension directly connected to deep freediving. This is not a watch that simply evokes adventure: it was born from one.

What are the characteristics of the ZRC Grands Fonds MN64 Titanium World Record?

Case of the ZRC Grands Fonds MN64 Titanium World Record

The case of the ZRC Grands Fonds MN64 Titanium World Record is made of grade 5 titanium. This material is especially coherent for a watch intended for extreme diving, as it combines lightness, mechanical strength and corrosion resistance. The case measures 41.5 mm in diameter and uses a monobloc construction, with screwed caseback and crown. ZRC also specifies that the titanium used is anti-magnetic according to the ISO 764 standard at 4,800 A/m. This architecture gives the watch a strong instrumental presence while preserving more comfort than one might expect from a diver capable of withstanding such pressure.

Caribbean blue dial and 3D LUMICAST indexes

The Caribbean blue gradient dial is one of the defining features of this World Record edition. Its colour evokes both the light of Egyptian waters and the gradual darkening that occurs as one descends below the surface. This idea is particularly coherent for a watch celebrating a dive to -145 metres. The raised indexes use 3D LUMICAST technology. They are produced through 3D printing from SLN-X1 luminous material in order to deliver optimal legibility in the darkness of great depths. The dial therefore combines a strong aesthetic dimension with genuine functional logic.

ECS® bezel and professional diver spirit

The bezel of the ZRC Grands Fonds MN64 Titanium World Record integrates the ECS® system, patented by ZRC. This unidirectional 60-click rotating bezel features a ceramic insert. The ECS® system was designed to facilitate rinsing after immersion in salt water, helping to evacuate impurities and salt crystals that can accumulate between the bezel and the case. This detail perfectly illustrates ZRC’s philosophy: thinking about the watch not only when it is new, but also when it is really used at sea, exposed to salt, sand and repeated constraints.

6 o’clock crown and Crown Protection System™

The crown positioned at 6 o’clock remains one of ZRC’s most recognisable signatures. On this MN64 Titanium World Record, it benefits from the Crown Protection System™, with a screw-down crown featuring dual sealing and an inverted thread. This position naturally protects the crown and prevents it from pressing into the back of the hand when the watch is worn. This solution, born from functional thinking, has become a strong aesthetic signature. It reminds us that the Grands Fonds was never designed as a simple style-driven diver, but as a true instrument built for demanding use.

Extreme water resistance and programmed-deformation caseback

The water resistance of this ZRC Grands Fonds MN64 Titanium World Record reaches a spectacular level. The watch is guaranteed to 3,000 metres and tested to 5,100 metres. This performance obviously far exceeds the needs of any diver or freediver, but it gives the watch exceptional technical credibility. The programmed-deformation caseback, exclusive to ZRC®, contributes to this ability to withstand extreme constraints. Rather than considering deformation as a flaw, ZRC integrates it into the design of the watch in order to better control how the case reacts to pressure.

5 mm domed sapphire crystal

The dial is protected by an imposing 5 mm domed sapphire crystal with anti-reflective treatment. This thickness is directly connected to the extreme vocation of the watch. The crystal does not merely protect the dial from scratches: it contributes to the overall resistance of the watch when subjected to considerable pressure. Its domed profile also recalls certain historical dive watches, while offering the performance and resistance of modern sapphire. This characteristic strongly contributes to both the visual and technical identity of the MN64 Titanium World Record.

Movement and performance

The ZRC Grands Fonds MN64 Titanium World Record is powered by the Sellita SW300-1 Élaboré automatic calibre. This Swiss movement runs at 28,800 vibrations per hour, or 4 Hz, has a stated maximum amplitude of 315 degrees and offers a 56-hour power reserve. The functions are deliberately reduced to the essentials: hours, minutes and seconds. This absence of superfluous complication perfectly matches the spirit of the watch. On a diver this instrumental, priority is given to legibility, robustness and reliability rather than the accumulation of indications.

FKM strap and titanium buckle

The MN64 Titanium World Record is fitted with an FKM rubber strap, paired with a titanium pin buckle. This choice is particularly coherent for an extreme diver. FKM is appreciated for its resistance, comfort and behaviour under environmental constraints. ZRC designed this strap by drawing inspiration from the appearance of its metal bracelets, preserving visual continuity between case and strap. The combination of titanium and FKM reinforces the instrumental vocation of this edition while making it genuinely wearable every day.

ZRC Grands Fonds MN64 Titanium World Record: an extreme diver born from the field

With the Grands Fonds MN64 Titanium World Record, ZRC offers a watch that directly connects sporting performance and watchmaking engineering. The grade 5 titanium monobloc case, 3,000-metre water resistance, 5,100-metre testing, Caribbean blue dial, 3D LUMICAST indexes, 6 o’clock crown, ECS® system and FKM strap create an extremely coherent dive watch. Its 50-piece limited production further reinforces its special character, but its main interest lies elsewhere: it celebrates a real performance achieved by a freediver who personally tested the ZRC universe at depth.

Conclusion

The ZRC Grands Fonds MN64 Titanium World Record is aimed at enthusiasts looking for an extreme, rare Swiss diver carrying a genuine sporting story. Thanks to its grade 5 titanium case, spectacular water resistance, Caribbean blue dial, 3D LUMICAST indexes and 50-piece limited production, it offers a particularly powerful interpretation of the contemporary tool watch.

Dialicious owner reviews are a relevant way to choose the watch that truly suits you.
