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 2014 Patek Philippe expands its collection with a further complication. This particular model is the Nautilus Travel Time Chronograph ref 5990. All stainless steel three part 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. Features include second time zone, date, local and home night/day indicators and 60-minute chronograph. Black gradated horizontal pinstripe dial with applied gold markers and transferred white detailing. Finished with a sapphire crystal glass and case back. Part of a private collection.
