When all other Sports wristwatches were slim and gold. Patek Philippe decided to create an elegant, but practical sports watch in stainless steel. In 1976, with the influence of Gerald Genta, Patek Philippe created the iconic “Nautilus”. Unusual with its porthole design, it is today one of the most sought after Patek Philippe timepieces available. The range has been changed, updated, discontinued, re-innovated and revisited and now in 2016 the model will celebrate its 40th Anniversary and show that it’s design will leave a legacy amongst new and old collectors alike. This particular Nautilus model is the ref 5712/1A. Made in an all hand finished stainless steel case and held on a hand finished and assembled stainless steel bracelet. Fitted with a Patek Philippe calibre 324 PS IRM C LU mechanical self-winding movement, features include date, moon phase, power reserve and small seconds. The dial is black-blue with horizontal pin stripe design and applied gold markers. The timepiece is finished with a sapphire crystal glass and exhibition case back.
