Patek Philippe Nautilus Flyback Chronograph Travel Time

A rare example of a complicated Patek Philippe model in steel, this Nautilus combines three highly sought-after complications: a self-winding flyback chronograph, a second time-zone display and a date hand coupled with local time. The elegant blue dial is enlivened by a sunburst motif and a black-gradient rim.

DIAL: Sunburst blue-gray with black-gradient rim, horizontally embossed, white gold applied baton-style hour markers with white luminescent coating. Local time hand: white gold rounded baton-style with white luminescent coating. Home time hand: white gold skeletonized rounded baton-style, white varnished.
