The Patek Philippe Annual Calendar Chronograph Ref. 5960/1A-001 is a true masterpiece of watchmaking and offers an elegant combination of functionality and aesthetics. This model features a stainless steel case that has a diameter of 40.5 mm, offering a striking presence on the wrist. The elegant white dial background stands out stylishly from the polished, applied indices and the red accents of the chronograph hand. The dial cleverly showcases the complex calendar movement, with an annual calendar function that automatically distinguishes between 30- and 31-day months, requiring only one adjustment per year. The date, day and month displays are arranged in symmetrical windows, while the 6 o'clock position houses a 12-hour chronograph counter. The movement, the caliber CH 28-520 IRM QA 24H, is an automatic mechanical movement that can be admired through the transparent sapphire crystal case back. It impresses with its high precision and fine workmanship, typical of Patek Philippe. Another highlight is the integrated stainless steel bracelet, which is equipped with a folding clasp and underlines the sporty, elegant look of this extraordinary watch. You receive a 1-year warranty on the functionality of the movement.
