Gérald Genta is a designer that needs little introduction to those in the watch world. Perhaps most famous for designing the Royal Oak and Nautilus pieces for Audemars Piguet and Patek Philippe respectively, Genta's designs also included the Universal Geneve Polerouter, the IWC Ingenieur, and the Seiko Locomotive. The last piece pays tribute to some of his most successful designs, and Genta had a very close relationship with the brand's president, Reijiro Hattori.
