A&S8300 – Ultrathin Flying Tourbillon

The A&S8300 calibre is only 2.97 mm thick and is one of the slimmest ever designed. The tourbillon carriage echoes the leading role John Arnold played in marine exploration during the 18th century. Its triangular shape evokes a sextant, while its double-arrow counterpoise represents an anchor. The point in the middle serves as a seconds marker, as the carriage completes a full rotation in one minute. In the background of the tourbillon, its bridge appears in the mainplate aperture, hand-engraved with a design inspired by the engravings found on John Arnold’s pocket watches. Crafted in 3N yellow gold, it blends with the gear train while creating an aesthetic contrast with the rest of the calibre.
