Ref. BA 811.0801 is from a group of watches in the ?Jeux d?Or? collection, designed by the famous Genevan jeweler Gilbert Albert in the late 1960?s and early 70?s. Gilbert Albert (born September 20, 1930) A renowned Genevan jewelry designer and artist. In 1955, at the age of 24, he began to apply his innovative talents to the design of wristwatch cases for Patek Philippe. Breaking away from traditional shapes, he introduced asymmetrical triangles and rhombic forms inspired by his passion for modern sculpture and works by his favorite artists, such as Brancusi and Mondrian. He also introduced textured organic surfaces on the asymmetrical shapes designed for the Patek Philippe ?Ricochet? collection. However, many of his more revolutionary designs of that time remained prototypes and were not produced in series. In 1962, Gilbert Albert established his own workshop, designing and producing jewelry under his own name. Over the years, he became very successful, both in Geneva and internationally, receiving numerous awards for his jewelry. Gilbert Albert's creations are exhibited worldwide.
