Introduced as part of the Nautilus Travel Time Chronograph family, the reference 5990/1A combines two of Patek Philippe’s most desirable complications in a single steel sport watch: a flyback chronograph and a dual time zone display. It’s built on the automatic caliber CH 28-520 C FUS and cased in a robust 40.5mm stainless steel Nautilus case. Like several other steel Nautilus references, the 5990/1A has since been discontinued, cementing its status as a fixed-supply collector’s piece.

The 5990/1A pairs a flyback chronograph with a dual time zone display in a 40.5mm steel case, powered by the automatic caliber CH 28-520 C FUS. It’s part of the discontinued Nautilus lineup, produced in both steel (5990/1A) and 18K rose gold (5990/1R) with blue or blue-black dial variants.
