Patek Philippe Complications Annual Calendar Chronograph Ref. 5905P-001 Encased in 42mm of solid platinum, this masterful timepiece features a striking blue sunburst dial adorned with applied white gold baton markers and epee hands. The dial integrates a flyback chronograph, a 60-minute counter, and a seamless annual calendar displaying day, date, and month via elegant apertures beneath the 10, 12, and 2 o’clock positions. A day/night indicator further enhances its practical sophistication.
At its heart beats the Patek Philippe Caliber CH 28-520 QA 24H, an automatic self-winding movement that combines chronograph precision with annual calendar convenience — requiring adjustment only once a year, at the end of February.
The watch is completed with a hand-stitched navy blue alligator leather strap featuring a platinum prong buckle, while the sapphire crystal case back reveals the impeccable craftsmanship within. Measuring 14.03mm in thickness, water-resistant to 30 meters, and paired with a timeless platinum bezel, this piece epitomizes Patek Philippe’s mastery of complications.
A sought-after creation among collectors, the 5905P represents 175+ years of chronograph expertise — a true connoisseur’s complication.
