The Patek Philippe Nautilus Travel Time Chronograph reference 5990/1A-001 is a sophisticated luxury sports watch that features a 40.5mm stainless steel case with a thickness of approximately 12.53mm. Introduced in 2014 to succeed the reference 5980, this model maintains the iconic rounded octagonal bezel and porthole-inspired architecture designed by Gerald Genta. The dial is characterized by a black-to-grey gradient finish with horizontal embossing, adorned with white gold applied hour markers and luminescent coating for enhanced legibility. It is powered by the self-winding caliber CH 28-520 C FUS, which is visible through a sapphire crystal case back and offers a power reserve ranging from 45 to 55 hours.
The timepiece integrates several practical complications, most notably a flyback chronograph and a dual time zone system. The Travel Time function utilizes two central hour hands to indicate local and home time simultaneously, supported by two separate day/night apertures labeled Local and Home. Local time can be adjusted in one-hour increments using pushers cleverly integrated into the left side of the case. Additionally, the watch features an analog pointer date at the 12 o’clock position that is coupled with local time, and a 60-minute chronograph counter at 6 o’clock. Its construction ensures a water resistance of up to 120 meters, making it a robust choice for frequent travelers.
General reviews of the 5990/1A-001 often highlight its impressive technical prowess and the seamless integration of complex functions into the classic Nautilus aesthetic. Collectors frequently praise the watch for its balance of utility and prestige, noting that it offers a more complicated alternative to the standard 5711 while remaining more accessible than the perpetual calendar models. However, some critics point out that the additional complications and the necessary case thickness of 12.53mm result in a bulkier profile compared to original Nautilus designs, which can affect its overall symmetry and traditional thinness. Despite these observations, it remains a highly coveted and valuable asset within the luxury watch market.
