The Excalibur Knights of the Round Table is a quest involving among the highest degree of know-how in all that a watch can offer: design, technique and exclusivity. The very recognizable face of the watch is made of twelve micro-sculptures - the Knights - placed around a dial - the Table. The Knights are handcrafted and represent the 12 characters involved in the quest. The table is made of gems or precious materials or materials requiring specific techniques, and symbolizes the unity and equality of the Knights. Underneath the face of the watch is an automatic calibre, manufactured in the Roger Dubuis workshops and certified by the Poinçon de Genève, one of the most demanding certifications in Haute Horlogerie.Case Pink gold* case with sapphire crystal with anti-reflective coating Pink gold* open case back with sapphire crystal Pink gold* bezel with sapphire crystal ring Pink gold* and green Murano glass crown *Pink gold 750/1000 Size: 45mm Water Resistance: 3 bar (30 m) Dial The crust is made of green Murano glass - the magma is a black varnish - the knights are in pink gold, each knight is different - the flange is made of green Murano glass Main material: Pink Gold 18K Strap According our non-exotic policy, Excalibur collection is adorned with a premium calf leather strap, built in volume to follow the design of the case and the movement.
