Patek Philippe Nautilus Chronograph

The Patek Philippe Annual Calendar Flyback Chronograph 5960/1A-010 brings together one of the manufacture’s most important in-house chronograph calibres with the everyday versatility of stainless steel. Its 40.5 mm steel case, blue dial, and integrated steel bracelet deliver a contemporary sports-luxury aesthetic while preserving the refinement for which Patek is known.

At a glance, the dial reveals a full annual calendar with day, date, and month apertures, a power-reserve indicator at 12, and a signature monocounter at 6 o’clock combining 60-second, 30-minute, and 12-hour chronograph functions plus a day/night display. Inside, the automatic CH 28‑520 IRM QA 24H calibre features a column-wheel, vertical-clutch flyback chronograph, 21k gold rotor, and a 45–55 hour power reserve, all visible through the sapphire caseback.

For the collector seeking a modern, steel Patek with true technical substance and strong future collectability, the 5960/1A-010 stands out as one of the most compelling references in the brand’s recent history.
