Arnold & Son extends its Instrument Collection by presenting two new versions of its UTTE tourbillon. With the A&S8200 movement measuring just 2.97 mm thick and the final cased watch a mere 8.34 mm, the UTTE is one of the thinnest tourbillon wristwatch ever produced. The calibre A&S8200 was developed designed and manufactured entirely in house at the brand’s La Chaux-de-Fonds workshops.
The alluring, timeless lines of the stepped 42 mm case, which tapers from the top to the bottom, imbue this watch with an austere elegance. While the movement diameter is 32 mm, the tourbillon cage is a massive 14 mm in diameter – thus occupying almost half of the movement space for impressive visual appeal.
The UTTE is created in either 18-carat red gold or palladium (a rare alloy in the watch world). Each movement is finished in a colour to complement the case colour, and each features a different Côtes de Genève pattern. The 18-carat red gold case watch houses the movement treated in rhodium and decorated with Côtes de Genève rayonnantes.
The tourbillon bridge of the 18-carat red gold UTTE is entirely hand-engraved by Arnold & Son’s master engraver. The palladium UTTE version houses a NAC grey treated movement decorated with a straight Côtes de Genève pattern for a bold, contemporary appeal.
