One model in the Excalibur collection adds a precious touch to its daring designs. The Excalibur 36 in pink gold and set with a halo of 672 diamonds (approx 4.78 carats) sparkles with the light of a thousand fires. Its aesthetic codes- dynamic shapes, sharp angles, powerful design – give it an allure that links refinement and beautiful watchmaking, without affecting the Roger Dubuis signature in any way.
