One counter instead of three, which is the whole idea.
The 5980 was the first Nautilus chronograph, and its defining decision is what is not on the dial. Instead of separate minute and hour counters, Patek uses a single monocounter at six o'clock that reads elapsed time up to sixty minutes on two concentric scales. The dial stays clean, the Nautilus proportions survive, and the watch does not end up looking like a chronograph wearing a Nautilus case.
The movement is calibre CH 28-520 C, self-winding with a 21 ct gold rotor, and the chronograph is a flyback. In rose gold the brown gradated dial is the pairing Patek keeps coming back to — warm against the case in a way the blue and black dials are not.
It is a gold sports chronograph on an integrated gold bracelet, which puts it in small-production territory. This is a network search, and the condition of the bracelet will matter as much as the condition of the watch.
