Patek Philippe Nautilus 5990

The Patek Philippe Nautilus 5990/1R-001 is a complicated model in rose gold with a 40.5 mm octagonal case and sapphire crystal. It features a self-winding flyback chronograph, Travel Time (GMT) display, and a date indication set by hand and coupled with local time, presented on a blue sunburst dial. The chronograph function is driven by the automatic calibre CH 28-520 C FUS, which combines a column-wheel drive with a vertical disk clutch and offers a 55-hour power reserve. The case provides water resistance to 30 meters.
