This iconic work of Aztec art proudly adorns the new X-TREM-1. This timepiece including the "Stone of the Sun" in relief, made of solid gold entirely hand-engraved, will be offered as a Unique Piece at the SIAR 2020. Driven as ever by a determination to present avant-garde timepieces, 5N red gold and black grade 5 PVD titanium were the metals chosen to make the case of this new version of the X-TREM-1 Azteca. The sapphire tubes have been replaced by cylindrical ring-bound tubes housing mobile stainless steel spheres indicating the time. The X-TREM-1 Azteca is a fine example of this approach that involves using a system driven by magnetic fields to display the hours and minutes.

The challenge was bold and some might say a little crazy: How could someone possibly think about introducing a magnetic field —the archenemy of horological mechanisms— into the heart of a watch? The Christophe Claret team has done just that by creating a system where two small steel spheres —hollowed to make them lighter and encased within two 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 millimeter in diameter. The resistance of the thread has been tested in the Manufacture Claret on an accelerated-wear simulator corresponding to 60 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 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.
