Swiss luxury watch brand Arnold & Son extends its Instrument Collection with the addition of the new UTTE Skeleton. Measuring just 8.34 millimetres in thickness and equipped with the new A&S8220 movement, this brand new creation is currently the thinnest skeleton tourbillon watch available in the market.
Developed, designed and manufactured entirely in house at Arnold & Son’s La Chaux-de-Fonds workshops, it is housed in an elegant 42-millimetre, red gold 5N case. This exquisite creation is available in a limited edition of just 50 timepieces.
8.34 millimetres in thickness with the two sapphire crystals (7.03 without), the UTTE Skeleton is the thinnest skeleton tourbillon watch on the market.
In their quest for ultimate perfection, harmony and transparency, Arnold & Son’s design engineers have effectively reinvented the A&S8200 calibre to create the A&S8220 calibre. The new calibre preserves the unique features that set the A&S8200 calibre apart: it is thin, boasts a large, three-dimensional tourbillon cage and has a long power reserve.
The tourbillon cage itself has also undergone a total revision, and the new skeleton design makes it much easier to appreciate the choreography of the pallets and escape wheel in action. At the same time, the curved, spherical design and aesthetic three dimensionality of the tourbillon typical of the UTTE models have been preserved. The movement itself is 32 millimetres across while the tourbillon cage measures a massive 14 millimetres and occupies a dominant position in the lower half of the dial.
In keeping with the overall exclusivity of the timepiece, the movement has haute horlogerie finishing that includes: the main plate and bridges are made of nickel silver and decorated with Côtes de Genève rayonnantes with chamfered and polished edges; the steel parts, gears and ratchets are satin-finished with chamfered and polished edges; the tourbillon cage’s edges are also fully chamfered and polished by hand; the screws have bevelled and polished heads; and jewels with polished countersinks.
Viewed from the side, the 5N red gold case is stepped and tapers from top to bottom, the widest section accommodating the extra-large glass with the lower part narrowing to fit snugly on the wrist.
