Patek Philippe Nautilus 5990/1A-011
Patek Philippe Nautilus 5990/1A-011
The Ref. 5990/1A-011 Nautilus Travel Time Chronograph is one of Patek Philippe’s rare stainless steel timepieces. It now features a striking new blue sunburst dial, enhanced by a subtle black gradient around the edge.
Powered by the self-winding calibre CH 28-520 C FUS, this model brings together three highly practical and intuitive complications: a flyback chronograph, a Travel Time function displaying two time zones with separate hour hands (the skeletonised hand indicating home time), and an analogue date at 12 o’clock, synchronised with local time.
