Some watch brands take years to reach a level of desirability, while others become legends almost immediately after creating their first watches. One such brand is Philippe Dufour. Born and educated in the Vallée de Joux, he worked for Jaeger LeCoultre, Gerald Genta, and with his growing reputation as a complication specialist, was commissioned by Audemars Piguet to create five grande sonnerie pocket watch movements. In 1996, Dufour introduced his iconic Duality, the world’s first wristwatch incorporating a double escapement. Featuring two independent balance wheels compensated with a central differential gear, the mechanism improves accuracy while also countering the effects of gravity. He initially planned to produce 25 examples, however only nine were made including the present watch with the extraordinary number ‘00’ - the very first Duality made by the master himself. Phillips is extremely proud to offer this Duality, one of a mere handful of Philippe Dufour watches ever to appear at auction. This example is preserved in wonderful condition and is absolutely complete, accompanied by its original certificate, brochure, and fitted presentation box. A modern masterpiece in every way, the present lot is an extremely rare opportunity to obtain one of the rarest, most important, and most sought after timepieces created by a living legend.
