Annual Calendar Chronograph 5905/1A - Green Dial - Full Set (Like New)

The 5905/1A is one of the most accomplished complications in Patek Philippe's steel sports catalogue - combining an annual calendar with a flyback chronograph in a 40.5mm case that wears with surprising elegance on the integrated bracelet. This Swedish-sold example presents in like-new condition, with factory protection films still present on the clasp and bracelet, and the deep olive-green sunburst dial showing no signs of use.
