Roger Dubuis: Excalibur pierced tourbillon/2010

Equipped with the brand new self-winding mechanical movement, one of the collection’s very latest models, the pierced tourbillon, reveals both its micro-rotor and flying tourbillon. The rose gold fillets outline the mother-of-pearl area on a dial designed with a circle theme and accentuate the strength of the large Roman numerals. The rose gold case is complemented by a hand-sewn alligator strap fitted with a rose gold folding clasp. This exclusive model comes in a single limited series of 88.
