CLERC Hydroscaph H140 Carbon Limited Edition Chronograph

Swiss luxury watch maker CLERC unveils the new Hydroscaph H140 Carbon Limited Edition Chronograph, an exceptional multi-functional diving timepiece featuring an exclusive central-display chronograph movement and a high-tech case designed to be fully functional in deep waters and made of DLC-coated steel together with NTPT® carbon, a futuristic material. Issued in a 140-piece limited edition to mark the anniversary of the Geneva-based Maison, the Hydroscaph H140 Carbon Chronograph offers a water-resistant to 500 metres.

Entirely developed and produced in Switzerland by North Thin Ply Technology, new high-tech material called NTPT® carbon was initially intended for making racing-boat sails. It made a noteworthy stage-entrance in the America’s Cup, the legendary competition that was won twice in a row by Switzerland’s Team Alinghi. The properties of NTPT ®carbon, which is notably twice as resistant to micro fissures than any other composite material, account for its current use in other cutting-edge fields such as aeronautics, the aerospace industry and Formula 1 motor racing.

Composed of multiple ultra-thin carbon fibre layers with a maximum thickness 30 microns, NTPT ® is impregnated with resin before being woven in such a way as to modify the direction of the weft by 45° between each layer. After subsequent heating, the material lends itself to machining better than any other composite, paving the way for all kinds of possibilities in the manufacture of high -precision components.

Carbon NTPT® not only offers peerless rigidity, but is also particularly attractive, since the weaving operations create mottled effects that are different in each case and thus give each model its distinctive character.

The Clerc Hydroscaph H140 Carbon Limited Edition Chronograph boasts a highly complex and exceptional 103-part case which is flanked with lateral reinforcements and a construction ensuring water resistance to 500 metres. The rotating bezel with its emblematic octagonal lines is protected from any involuntary activation by an exclusive device: a built-in retractable flap on the case middle must first be deployed before pivoting the bezel via a dedicated crown at 10 o’clock ; and once the flap is returned to its initial position, the bezel is once again secured against any risk of accidental deregulation.

The 3 o’clock time-setting and winding crown ensures an optimal grip. The broad and partially cut-out chronograph pushers react to pressure by pivoting around a lateral axis acting as a lever, thus ensuring uniquely smooth handling and excellent precision for short-time measurements. Comfort is also a strong point, since the mobile lugs ensure perfect adjustment on the wrist, even when worn over a neoprene diving suit.

The sapphire crystal case-back reveals the beauty of the exclusive C608 calibre beating at the heart of the Hydroscaph H140 Carbon Limited Edition Chronograph. This authentic Haute Horlogerie ‘engine’ beats at the high frequency of 4 Hz (28,800 vibrations/hour) and orchestrates an unusual short-time read-off mode via a central display. Rather than indicating the minutes on a counter, the chronograph is equipped with two hands ensuring perfect and intuitive legibility: a central chronograph seconds hand as well as an additional hand counting off the minutes. The finely tuned mechanism of the self -winding C608 movement also powers a 24-hour day/night indication that is especially useful when adjusting the date.

The indications stand out with surgical precision against an elegant dark grey dial. The cool grey Superluminova coating on the hands and hour-markers provides high legibility during poor light conditions.

Clerc Hydroscaph H140 Carbon Limited Edition Chronograph is supplied with a new water-resistant carbon fibre-textured strap.
