Unveiled in 2012 and since interpreted through a variety of limited editions, the X-TREM-1 series is one of the best sellers from Christophe Claret manufacture. This year, the watchmaker joins forces with American lifestyle brand StingHD and presenting a new variation of this watch in an 8-piece limited edition. Like the original X-TREM-1, this new timepiece combines an inclined flying tourbillon with retrograde hours and minutes display system based on magnetic fields. The new X-TREM-1 – StingHD comes dressed in a black PVD treated titanium case, a skull on the tourbillon carriage, and a stingray leather or personalized strap. In an additional spirited touch, breathing on the sapphire crystal reveals a skull motif.
The X-TREM-1 has always been an anti-conformist by nature, starting with the innovative technical refinement of its retrograde hours and minutes display. For the first time in the field of mechanical watch making, the X-TREM-1 timepiece makes use of a magnetic field – the arch enemy of horological mechanisms – into the heart of a watch.
It made possible with a system where two small steel spheres – hollowed to make them lighter and encased within two sapphire tubes placed to the right and left of the caseband – are controlled by precision magnetic fields generated by two miniature magnets moved by cables. The cables are incredibly flexible, made from hundreds of Dyneema nanofibers all contained within an ultra-high-strength polyethylene gel, capable of withstanding tensile forces of up to a kilo. The entire thread is thinner than a human hair (4 hundredths of a mm in diameter). The resistance of the thread has been tested in the Manufacture Claret on an accelerated-wear simulator corresponding to six years of operation. The spheres have no mechanical connection with the movement, with each one floating inside the two tubes and creating outstanding horological magic. This technology was developed with the School of Business and Engineering Vaud (HEIG-VD) in Yverdon-les-Bains, and a team headed by Professor Besson.
The entire construction and finishing of this timepiece meets the extreme demands systematically imposed by Christophe Claret. Ultra-light titanium was used for the three-dimensional curvex mainplate and the bridges. The flying tourbillon is fitted with double ceramic bearings to enhance its shock-resistance. It is inclined at a 30-degree angle in order to make it even more clearly visible to the wearer. The hand-wound watch draws its energy from two barrels enabling the use of a sophisticated display without disturbing the rate of the tourbillon, and thus the accuracy of the watch. The first barrel is reserved for the tourbillon, the second for the hours and minutes.
This model comes with two straps designed by StingHD: one in black stingray leather, and the other which can be personalized by its owner. In addition, the presentation box also includes a matching, handcrafted bracelet adorned with a black diamond encrusted skull with ruby eyes.
