Ultrathin Tourbillon

The tourbillon, a mechanism added to the mechanics of a watch escapement for unmatched precision, is here, in the Arnold & Son Ultrathin Tourbillon collection, fully realized as one of the thinnest tourbillons ever produced. Designed with offset hours dial and tourbillon aperture, choose from platinum/green, gold/silver opaline, gold/blue, or gold/skeleton, beneath a domed sapphire crystal.
