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. In 2006 Patek Philippe launched a new model to the Nautilus family, in honour of the ranges 30th anniversary. The Nautilus Chronograph, ref 5980 was created. Made in an all stainless steel hand finished case and held on a Manufacture made stainless steel bracelet. Fitted with the highly complicated and decorated Manufacture calibre CH 28-520 C mechanical self-winding movement with 12 hour chronograph and date functions. Silver-white horizontal pin stripe dial with applied gold numerals and transferred detailing. Water resistant to 120 metres and finished with a sapphire crystal glass and exhibition case back.
