First presented by Christophe Claret in 2012, the X-TREM-1 is a timepiece that well represents the challenge of finding new ways of telling the time taken by the haute horlogerie manufacture based in Le Locle.
It is now available a new version of this innovative watch, the X-TREM-1 Chocolate, featuring a red gold and grade 5 titanium case treated with chocolate-colour PVD, plus an alligator-skin strap of the same brown hue.
— the names stands for eXperimental Time Research Engineering Mechanism — displays hour and minutes by means of two 4mm-diameter hollowed steel spheres isolated within sapphire tubes on both sides of the case band. The two spheres appear to be floating in their respective tubes but they are actually controlled by magnetic fields generated by two magnets moved by ultra-thin surgical cables, made from hundreds of Dyneema nanofibres all contained within an ultra-high-strength polyethylene gel, capable of withstanding tensile forces of up to a kilo.
The tourbillon movement and the time indication gear trains each have their own independent barrel to optimize power distribution and duration. The two barrels are visible on the back case. The dimensions of the rectangular case are: 40.80 x 56.80 x 15 mm
Issued in limited editions of 8 pieces for each version, the Christophe Claret X-TREM-1 is also available with cases in white gold/titanium, red gold/titanium, and platinum/titanium with a starting price of around Swiss Francs 265,000. The pictures below show the white gold and red gold versions.
