Arnold & Son Chronometry Ultrathin Tourbillon Red Gold 41.5mm Mens Watch Blue

Ref. 1UTBR.U01A.C209A

The 41.5mm case in 18-karat red gold is kept remarkably shallow at 8.30mm, housing the manual-winding A&S8300 calibre at just 2.97mm thick. The blue "Cosmic Grené" dial uses gold powder mixed with blue aluminium sparkles to produce a finely textured, subtly luminous surface. An off-centre domed white mother-of-pearl subdial at 12 o'clock carries hours and minutes behind a 4N gold-plated ring with Roman numerals, while the flying tourbillon sits open at 6 o'clock, its titanium carriage shaped after a marine sextant with an anchor-form counterpoise. Openworked golden hands complete the layout. The domed sapphire crystal features anti-reflective coating on both sides, and the open caseback reveals the movement beneath. A blue alligator strap, hand-stitched with 18-karat red gold thread, fastens with a folding clasp bearing a matching red gold cover. Power reserve stands at 100 hours.
