The Patek Philippe Nautilus 3700 is the founding member of the iconic Nautilus lineup. Designed and drawn out in less than 30 minutes by Gerald Genta in 1974 at the Basel Fair, Genta was also responsible for the Royal Oak, IWC Ingenieur, Omega Constellation, amongst others. Here we have the 3700/11 in two tone metals (steel and 18K yellow gold). The overall condition is perfect with little to no signs of dents or scratches.
