Gerald Genta, who collaborated with many renowned Swiss watch manufacturer such as Patek Philippe and Audemars Piguet, started his own brand in 1969 which was known for its elaborate movements and craftsmanship - in particular his “sonneries” models. He was known to hand design his watches and the development process could take up to 5 years to complete. This tourbillon minute repeater catches the eye with its decoratively hand engraved case and movement, requiring immense amount of dedication and astounding levels of craftmanship.
