Patek Philippe presents the Nautilus Travel Time Chronograph Reference 5990/1 in a generous rose gold version contrasting with the sunburst blue dial featuring an embossed horizontal pattern and applied hour-markers. The baton-style hands are in rose gold with a luminescent coating. This new model combines three highly sought-after complications: a self-winding flyback chronograph, an easy-to-use Travel Time function (dual time-zone), and a date display, coupled with local time.
