Hydroscaph GMT Power-Reserve
Chronometer Built for extremes
In direct line from its emblematic collection of Hydroscaph diver’s watches, Clerc Genève presents its new exploration machine: the Hydroscaph GMT Power-Reserve Chronometer. Designed to withstand the extreme conditions of deep-sea diving, the Hydroscaph GMT Power-Reserve Chronometer is a sophisticated adventurer that is just at home in the abyss as on the wrist of a stylish globetrotter. Its ultra-technical case topped by an exclusive bezel – avoiding an accidental deregulation while diving – is equipped with an automatic helium release valve guaranteeing water resistance to 800 metres, while its patented lateral reinforcements protect it from shocks. The remarkably precise and reliable new Clerc Calibre C610 is certified by the Swiss Official Chronometer Testing Institute (COSC). This mechanical self- winding movement endowed with a 42-hour power reserve notably drives an oversized 24-hour dual-time display at 6 o’clock.
An authentic benchmark in terms of advanced technologies and Swiss craftsmanship, the Hydroscaph GMT Power-Reserve Chronometer expresses a contemporary form of haute horlogerie driven by a daringly pioneering spirit. Its complex architecture and powerful appearance make this exceptional timepiece the ultimate companion for extreme divers, lending itself to the most fascinating human adventures; as well as a luxurious accessory featuring a distinctive structure. The forcefully elegant 83-part high-tech case with patented lateral protections is capable of withstanding the extreme conditions prevailing during an 800-metre immersion into the abyss. Like all Hydroscaph models, it has successfully passed a set of particularly stringent tests designed to ensure it meets standards extending well beyond conventional norms: traction, shocks, visibility, magnetism, water-tightness in deep waters, resistance to seawater and corrosion. Driven by a futuristic mindset and characterised by its uncompromising construction, the Hydroscaph GMT Power-Reserve associates the GMT function with the power-reserve indication, making this high-tech diving instrument a dream partner for long-distance travellers. A great favourite among divers, the GMT function is an ideal companion for these explorers of the extreme constantly looking for the best spots on the planet.
A resolutely modern take on haute horlogerie
Impelled by the visionary spirit of Gérald Clerc, ably representing the fourth generation of a watchmaking dynasty imbued with technical excellence and innovation since 1874, the new Hydroscaph GMT Power-Reserve Chronometer is destined both to offer impeccable functionality in deep waters and to adorn the wrist of men with a uniquely distinctive style. Heir to 140 years of family tradition, Gérald Clerc is building the haute horlogerie of tomorrow on this prestigious historical foundation. Looking resolutely to the future and powered by a flair for innovation, Gérald Clerc conceived the new Hydroscaph GMT Power-Reserve Chronometer as a technical, powerful instrument imbued with extreme refinement expressed through finely balanced lines and perfect execution.
Performance and reliability serving the spirit of adventure
One of the most complex currently on the market, the construction of the ultra- technical case of the Hydroscaph GMT Power-Reserve Chronometer comprises 83 individually machined parts ensuring that each individual case is truly unique. Developed and fine-tuned by dint of formidably demanding tests, the high-tech case guaranteed water-resistant to 800 metres reflects an uncompromising approach to both functionality and aesthetics. The generously sized 43.8 mm case middle is equipped with an automatic helium release valve, while its iconic exclusive rotating bezel – a perfect circle in a perfect square – is protected from any inadvertent activation by an exclusive device. Pivoting the bezel by means of the dedicated crown at 10 o’clock requires prior deployment of a retractable flap built in to the crown. Once retracted, the bezel is thus securely locked and protected from any accidental deregulation when diving. The time-setting and winding crown at 3 o’clock provides an optimal grip, while the glareproofed 4 mm sapphire crystal protects this luxurious high-tech watch from any scratches or violent impacts.
An exclusive ‘engine’ for a unique exploration machine
A powerful ‘motor’ meeting the demanding standards of Haute Horlogerie, the exclusive self-winding Clerc C610 movement driving the new Hydroscaph GMT Power-Reserve Chronometer has sailed with flying colours through the merciless tests procedures conducted by the Swiss Official Chronometer Institute, thereby joining the extremely select circle of authentic chronometers certified by this prestigious authority. This remarkably precise calibre beats at the brisk rate of 28,800 vibrations per hour and has a comfortable 42-hour power reserve. While undeniably complex in terms of its construction and its standout performance, the exceptional mechanism of the Hydroscaph GMT Power-Reserve Chronometer delivers essential functions that are extremely useful in daily life: alongside the hours, minutes, and central seconds hands, this watch also shows a date through an aperture at 3 o’clock, complemented by the power-reserve indication at 12 o’clock and the dual-time display at 6 o’clock – adjustable via a dedicated pusher at 4 o’clock. In addition, this finely crafted mechanism bears an original circular-grained and openworked oscillating weight with a compelling design that is visible through the sapphire crystal case-back.
Depth effects and perfect readability
The deceptively simple dial of the Hydroscaph GMT Power-Reserve Chronometer in fact reflects extremely accomplished stylistic research. The precision and the optimal legibility of the indications, combined with the complex case construction, add to the strength of this iconic model. The individually crafted 3D numerals and hour-markers are bevelled to facilitate the sweep of the hours hand. Their subtly trapeze-shaped lines proclaim an authoritative style and ensure perfect read-off from any angle. In a reference to marine depths, the dual-time display stands out clearly on an oversized mother-of-pearl counter. Whether on dry land or at the bottom of the sea, the readability of this 3D face remains optimal thanks to a Superluminova coating applied to the hour-markers and the hands with their post-industrial look.
Style power and a wealth of expressive variety
Building on its inimitable design, the Hydroscaph GMT Power-Reserve Chronometer comes with a case in a choice of high-density polished steel, solid steel with black Diamond Like Carbon treatment – an extremely hard and scratch-resistant coating – or in 18K red gold and black DLC-coated steel. Several dial variations – white, midnight blue, chocolate brown or black – provide a wide array of alternative faces. A vulcanised rubber or alligator-finish rubber strap secured by a folding clasp complete with safety pushers lends an ultimate touch of refinement to the Hydroscaph GMT Power-Reserve Chronometer. Seamlessly integrated with the case, it acts as an extension of the Hydroscaph collection’s signature mobile lugs, designed to ensure a perfect fit on the wrist even over a diving suit.
Embodying a futuristic, finely crafted expression of watchmaking built on a powerful and distinctive character, the Hydroscaph GMT Power-Reserve Chronometer is endowed with the excellence and the innovative spirit that have been forging the destiny of Clerc Genève for more than 140 years.
