Arnold & Son Watch UTTE Red Gold Limited Edition 1UTBR.U01A.C209A.

Limited Edition of 28 pieces.

The ultrathin tourbillon by Arnold & Son is offering two new designs. They feature a new type of dial with tinted gold and aluminium sparkles to match their precious cases, which have also been redesigned. In 5N red gold or 950 platinum, the cases are just 8.3 mm thick beneath their domed sapphire crystals. The offset display and the tourbillon aperture echo the way in which information was arranged on John Arnold’s marine chronometers. After reworking the structure and appearance of the rotating regulating organ, the power reserve now lasts at least 100 hours – an outstanding and noteworthy performance for an ultrathin tourbillon timepiece.

To give the Ultrathin Tourbillon a new unique and refined design, Arnold & Son has focused on materials and techniques that highlight the precious appearance of this finely honed tourbillon. The 41.5 mm cases in 5N red gold or 950 platinum have been redesigned, making them even slimmer and more refined. The bezels have been reduced to a fine metal band, the sapphire crystals are domed, and the transparent case backs have been screwed down.

At the heart of the Ultrathin Tourbillon lies the A&S8300 calibre, whose architecture and finesse characterise this collection. At just 2.97 mm thick, this tourbillon with extremely refined finishes is one of the slimmest ever designed.
