Patek Philippe Complications 5935A-001 World Time Flyback Chronograph

In-Depth Review

The Patek Philippe 5935A-001 World Time Flyback Chronograph in stainless steel sent shockwaves through the collecting community when it debuted in 2023. Patek Philippe in steel has always been a potent combination, and the 5935A pairs two of the brand's most celebrated complications -- the world time and the flyback chronograph -- in a single 41mm case that immediately became one of the most desirable references in the current catalog. The Caliber CH 28-520 HU is an automatic movement that integrates both complications seamlessly, with the world time cities disc surrounding the blue-grey gradient dial and the chronograph operating via a column-wheel flyback mechanism that allows instant reset and restart.

The blue-grey gradient dial is beautifully executed, providing a modern and slightly sporty character that complements the stainless steel case. A blue composite strap keeps the watch comfortable and lightweight, though some collectors wish Patek had offered a steel bracelet option. The 30-meter water resistance is typical for Patek Philippe complications and signals that this is a travel watch, not a sports watch. The flyback function is genuinely useful for anyone timing multiple events in sequence, and the world time complication -- originally pioneered by Louis Cottier in collaboration with Patek Philippe -- is the brand's signature.

With an MSRP of $93,500, the 5935A trades near $180,000 on the secondary market, nearly doubling its retail price. This premium is driven by the extreme scarcity of Patek Philippe steel complicated watches, a category that has produced some of the most valuable modern watches ever sold at auction. The closest competitor in terms of complication set would be the A. Lange and Sohne Datograph, though it lacks the world time function, or the Vacheron Constantin Overseas World Time, which lacks the chronograph. For the collector who wants two of haute horlogerie's greatest complications in one exceptionally rare steel package from the most revered name in watchmaking, the 5935A is the clear choice.
