Gilbert Albert 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 proto-types 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. Creations of Gilbert Albert, Ref. 3412-3413 (prototypes) and 3422-3424 (production) are illustrated in "Patek Philippe Wristwatches", by Martin Huber and Alan Banbery, 1998, pp. 78, 163, 187 and 188 and in the thematic sale "The Art of Patek Philippe", Antiquorum Geneva, April 9, 1989, pp. 45, 103 and 263. Tachisme The two first lots owe them asymmetrical shapes to the ?Tachiste? movement, a style of abstract painting popular in the late 1940s and early 1950s. It is characterized by the use of irregular blotches of color (from the French word "tâche", meaning "spot"), and pursued goals similar to those of abstract expressionism, favoring spontaneity over formal rigor. In 1953 the French painter and poet Jean Atlan described the philosophy behind Tachisme in this way: "there is a common source for the painter and the dancer, this common source is a certain manner of living rhythms... At the beginning there is a rhythm which tends to unfold itself: it is the perception of this rhythm that is fundamental and it is on its development that the vital quality of the work depends." Tachisme was primarily a French move-ment and possesses a characteristic elegance and lyricism.
