Arnold & Son unveiled the TES Tourbillon, a new timepiece which is part of the Royal Collection, where classic styling combines with leading-edge technology.
The meticulously hand-finished A&S8100 tourbillon calibre adopts sapphire and open-worked bridges to create a fascinating three-dimensional effect and offer to the owner the view of barrel and wheels, whose three-spoke characterising design can also be found in the tourbillon cage and the openings in the main plate.
The decoration of the main plate, skeletonised around the barrel and the tourbillon carriage, is inspired to an old guilloché pattern found on the cases of antique Arnold & Son pocket watches.
The winding system uses wheels with long and narrow spokes known as wolf’s teeth to improve the smoothness of the overall movement.
The hand-wound tourbillon movement has a power reserve of 80 hours and beats at 21,600 vibrations per hour.
The Arnold & Son TES Tourbillon is a limited edition of 28 pieces, in a 44 mm red gold case with a NAC (platinum alloy) grey main plate, individually numbered and engraved.
