FLYBACK CHRONOGRAPH. ANNUAL CALENDAR.

A resolutely sporty look

A rare example of a Patek Philippe complicated watch in steel, this self-winding flyback chronograph with Annual Calendar radiates a resolutely sporty look. The visually rhythmical sunburst dial features an elegantly casual olive green hue. The integrated bracelet is enhanced by contrasting polished and satin-brushed finishes. The Annual Calendar requires only one correction per year.
