Our Craft
Our three powerful Hydroscaph series (Central Chronograph, H1, and GMT) are run through a set of particularly stringent tests well above and beyond conventional norms at our Switzerland based testing facilities. These include traction, shock, visibility, magnetism, water-tightness, and resistance to seawater and corrosion.
Hydroscaph Cases
Performance and reliability serving the spirit of adventure. The Hydroscaph case corresponds to one of the most complex constructions in contemporary watchmaking. Developed in close cooperation with a team of underwater exploration professionals, it comprises 81 to 103 individually machined parts ensuring that each individual case is truly unique. Developed and fine-tuned by series of formidably demanding tests, the high-tech case is guaranteed water-resistant from 500 to 800 meters and reflects an uncompromising approach to both functionality and aesthetics.
The generously sized case – instantly recognizable by its iconic exclusive rotating bezel – forms a perfect circle in a perfect square and is protected from any inadvertent activation by an exclusive device. Pivoting the bezel by means of the dedicated crown 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 provides an optimal grip, while the glare-proofed 4mm sapphire crystal protects this luxurious high-tech watch from any scratches or violent impacts.
Hydroscaph Dials
Unique character revealed in every last detail. Beneath its apparent simplicity, the Hydroscaph dial reveals an undeniable aesthetic and technical appeal. The impact and the optimal legibility of the display combined with a complex construction add to the strength and readability of every model. The individually machined three-dimensional numerals and hour-markers proclaim a boldly assertive character. When viewed from the front, they appear slightly trapeze-shaped, while ensuring maximum readability from all angles. Like them, the hands also display a post-industrial look and are coated with Superluminova for perfect read-off even in the darkest abyss.
Hydroscaph Movements
The exclusive CLERC Calibre C609 emerged victorious from its immersion into the merciless set of tests conducted by the Swiss Official Chronometer Testing Institute and can thus rightly claim to be a COSC-certified chronometer – the most prestigious pledge of precision and reliability. Beating at a high frequency of 4 Hz, meaning 28,800 vibrations per hour, the C609 movement is simple in terms of its functions–hours, minutes, seconds, date–backed by a 42-hour power reserve, while featuring a highly demanding level of finishing. These resolutely fine watchmaking finishes, along with the open-worked oscillating weight, have become a signature of CLERC movements.
