Two special editions are joining the collection of Clerc Hydroscaph H1 diver’s watches. The deep black Hydroscaph H1 Chronometer Carbon Edition features a case combining the ultra-light, resistant character of carbon fibre with the strength of steel. The Hydroscaph H1 Chronometer Vancouver Bay Edition, made from high-density steel, celebrates the first underwater expedition marking the partnership between Clerc Genève and the manufacturer of private submersibles, Sub Aviator Systems. In terms of both development and testing, both have benefited from cutting-edge technologies and trials in extreme conditions, performed in the R&D lab of the world leader in marine technology. 

A high-tech case and a crystal-clear display

The extremely technical 81-part case of the Hydroscaph H1 Chronograph is one of the most complex on the market and its components are individually machined. It complies with formidable standards and delivers guaranteed water resistance to 500 metres. Its generous 43.8 (or 48 mm including case protectors) diameter is topped by the iconic octagonal rotating bezel with its exclusive locking device. Pivoting its dedicated 2 o’clock requires the prior deployment of a retractable flap. Once the latter is returned to its initial retracted position, the bezel is secured against any inadvertent deregulation during diving. The 4 o’clock time-setting and winding grown ensures an optimal grip, while the 4 mm-thick sapphire crystal protects from scratches and violent impacts.

The apparently simple dial of the Hydroscaph H1 Chronometer models reflects extreme care devoted to style and design. The individually fashioned, bevelled and subtly trapeze-shaped three-dimensional numerals and hour-markers ensure perfect read-off from any angle. Their optimal legibility is reinforced by a Superluminova coating applied to the hands and hour-markers with their post-industrial design.

A powerful exploratory engine

At the heart of these two new exploration machines beats the exclusive Clerc C609 calibre. This remarkably precise self-winding movement has successfully undergone the stringent tests performed by the Swiss Official Chronometer Testing Institute (COSC), thereby joining the select circle of authentic chronometers certified by this prestigious body. While undeniably complex with regards to its construction and its exceptional performance, it nonetheless radiates simplicity in terms of its functions, displaying only essentials: hours, minutes and seconds. Compliant in all respects with the demanding standards of Haute Horlogerie, it beats at the high frequency of 28,800 vibrations per hour and has a comfortable 42-hour power reserve. Finally, this finely crafted mechanism features the distinctive oscillating weight of Clerc movements and visible through the caseback fitted with twin sapphire apertures.

A laboratory unique in the world

The technical, powerful and supremely refined instruments composing the new Hydroscaph H1 Chronometer series are designed to meet all the demanding criteria of the ISO6425 norm governing the diver’s watch label. Like all Hydroscaph models, they have successfully passed a series of particularly stringent dedicated tests relating to traction, shocks, visibility, magnetism, water resistance in deep waters, as well as resistance to seawater and corrosion.

As part of its partnership with Sub Aviator Systems, the Maison Clerc enjoys access to the prestigious R&D lab of the underwater exploration pioneer. It thereby benefits from its scientific expertise that notably contributes to the development and fine-tuning of ever more advanced technical solutions capable of withstanding the extreme conditions prevailing at great depths. The collaboration also enables it to have tests performed in conditions identical to those used for the Sub Aviator Systems submersibles and other high-tech equipment, and thereby to tests the resistance and performance of diver’s watches in real-life situations.

The aesthetically balanced lines and perfect execution of the Hydroscaph H1 Chronometer models are matched by a vulcanised rubber or alligator-finish rubber strap, fitted with a folding clasp with safety pushers. Seamlessly integrated into the case, it smoothly extends the distinctive mobile lugs of the Hydroscaph collection, designed to ensure an optimal fit on the wrist, even over a diving suit.
