Patek Philippe Nautilus With Archive Papers 5980/1A-001

Patek Philippe Nautilus Chronograph reference 5980/1A-001 features a durable stainless steel case measuring 40.5 mm in diameter paired with an integrated stainless steel bracelet and a fold-over clasp. The watch is distinguished by its signature gradient blue-black dial with horizontal embossed bars, which fades from a lighter metallic blue in the center to a darker shade at the edges. The dial includes luminescent white gold hands and hour markers, a date display at the 3 o'clock position, and a unique co-axial monocounter at 6 o'clock that elegantly combines both 30-minute and 12-hour chronograph displays to maintain dial symmetry. Powering the timepiece is the self-winding Caliber CH 28-520 C movement and power reserve of up to 55 hours.
