 Swiss jeweler trained in jewelry design at the School of Industrial Arts in Geneva and then at the Beaux Arts in Geneva, Gilbert Albert,  joined Patek Philippe as a designer in 1955 where he became workshop manager. He opened his first boutique in the early 1960s and began a collaboration with Omega. He won numerous prizes and opened other stores around the world. His work is characterized by the use of unusual materials such as fossils, beetles, animal teeth, meteorites... Nature and the animal world in particular form an inexhaustible source of inspiration. Most of his creations are unique pieces.
