Patek Philippe Aquanaut 5164A: Travel Time Explained

The Patek Philippe Aquanaut 5164A pairs a rounded case and patterned strap with a useful travel complication. Its two central hour hands let the wearer keep home time visible while reading the time at a destination. The watch shown here is from our photo archive; this article is not a current stock listing.

Reading Home and Local Time

According to Patek Philippe’s Aquanaut Travel Time instructions, the solid hour hand shows local time and the open hand shows home time. Separate day and night indicators help distinguish morning from evening in each location. The date follows local time.

The side correctors move the local hour hand in one hour steps without changing the minute and second display. When both time zones are the same, the hour hands can overlap. Owners should use the correct manual and a demonstration for their exact watch before making adjustments.

What the Photographs Show

The exhibition caseback offers a view of the automatic movement and winding rotor. From the front, the local and home indicators sit above the date subdial. The patterned strap continues the dial’s gridlike design, giving the watch a consistent texture without a metal bracelet.

Assess the Individual Example

For a previously owned 5164A, ask for its reference documentation, service history and a demonstration of both time displays and the date. Check the strap fit and condition, clasp operation and any replaced parts. Do not assume specifications from another Aquanaut reference apply to this one.

The original water resistance rating is not proof of a used watch’s present sealing condition. Have suitability for water exposure assessed rather than treating the sporty appearance as permission to swim with it.
