For collectors seeking a definitive modern sports watch, the Patek Philippe Nautilus ref. 5990/1A-011 represents peak functionality within an iconic design. This dual time chronograph seamlessly merges practicality with prestige, solidified by its full set completeness (box, papers, warranty card, pusher pins) and rare Patek Philippe travel pouches.

Launched in 2014 as the successor to the 5980/1A, the 5990/1A-011 addressed a key collector demand: integrating travel time functionality with a flyback chronograph. Its Caliber CH 28-520 C FUS movement—adapted from the Aquanaut Travel Time—enables simultaneous tracking of two time zones while operating a high-precision stopwatch. The 40.5mm stainless steel case retains the Nautilus silhouette but innovates with recessed dual-time pushers at 8 and 10 o’clock, preserving the case profile.

Key Details for Discerning Buyers:

• Condition: Like new 
• Set: Complete set - Original box, papers, warranty card, pusher pins + Patek Philippe pouches (Could be given upon request)
• Dial: Blue sunburst with subtle linen texture (replaced discontinued Gray dial 5990/1A-001)
• Movement: Self-winding Caliber CH 28-520 C FUS with 55h power reserve
• Rarity: Among earliest blue-dial examples
• Why This Watch Matters

As noted in collector forums (Quora, Rolex Forums), the 5990/1A-011 solves a real-world problem: frequent travellers needing instant time zone adjustments without sacrificing chronograph utility. Its 11.6mm thickness—while noticeable—distributes weight evenly via the integrated bracelet, making it wearable for daily use. Market tracking shows steel Nautilus chronographs consistently appreciate, with full sets commanding 20-30% premiums (Grey market’s data).

This example’s like-new state and complete provenance make it a low-risk acquisition for serious collections. Few complicated Patek Philippe sports watches offer this blend of horological innovation and immediate recognizability.
