Our Take

One of the slimmest tourbillons in the world is shedding its adornments. Pared back to its purest expression, the Ultrathin Tourbillon Gold is elegantly revealed. Its vast dial displays an almost lunar silver-toned opaline finish, while the off-centred hours dial is made of genuine white opal. Nothing now distracts the eye from the hypnotic workings of the ultra-thin flying tourbillon – the signature of the collection.

The Ultrathin Tourbillon Gold is a harmonious timepiece housed in an 8.3 mm-thick case. Its dial with a wide opening has received a remarkably refined treatment that is unprecedented in the history of this model, an Arnold & Son icon.

The vast expanse of the dial features two apertures. One houses the hours dial and the other welcomes the visible elements of the A&S8300 calibre. The Ultrathin Tourbillon Gold expresses itself with elegance.
