Patek Philippe Nautilus 5980 Rose Gold 5980R-001

The 5980 is the chronograph Nautilus. Patek's current version, the white gold 5980/60G-001, has the same 40.5 mm by 12.2 mm case and runs on the self-winding flyback calibre CH 28-520 C, which gathers the 60-minute and 12-hour counts in a single subdial at 6 o'clock and shows the date at 3.

Among the other 5980s, the rose gold 5980/1R-001 has a black dial. The steel 5980/1A comes with a blue (5980/1A-001), black (5980/1A-014) or white (5980/1A-019) dial, and the 5980/1AR-001 mixes steel and rose gold with a blue dial. The Nautilus 5726 uses the same 40.5 mm size for an annual calendar with moon phases and a 24-hour indication instead of a chronograph, and is thinner at 11.3 mm.
