They both show a second time zone, but differ in how the wearer adjusts local time, their stated water resistance, power reserve and supplied strap options. The figures below are manufacturer specifications, not results of independent comparative testing.
At a glance: two exact references
| Specification | Patek Philippe Aquanaut Travel Time 5164G-001 | Vacheron Constantin Overseas Dual Time 7920V/210A-B334 |
|---|---|---|
| Case and material | White gold; 40.8 mm diameter; 10.2 mm thick. Patek Philippe specification | Stainless steel; 41 mm diameter; 12 mm thick. Vacheron Constantin US specification |
| Water resistance | 30 m; screw-down crown. Patek Philippe specification | 150 m. Vacheron Constantin US specification |

| Second-zone display | Solid central hour hand for local time; skeletonized central hour hand for home time; day/night indicators for both zones. Patek Philippe specification | Second time zone and day/night indication. The cited product page does not give equivalent step-by-step setting instructions. Vacheron Constantin US specification |
| Date | Hand date coupled to local time. Patek Philippe specification | Date at 6 o’clock. Vacheron Constantin US specification |
| Supplied wearing options | Integrated blue-gray composite strap. Patek Philippe specification | Steel bracelet with an interchangeable system; the cited page also lists rubber and grained calfskin leather straps. Vacheron Constantin US specification |
These details apply to the references shown, not every Aquanaut or Overseas. In particular, the Overseas comparison is the steel 7920V/210A-B334; specifications for other materials and variants can differ.
How the travel-time controls differ
Aquanaut: adjust local time in one-hour steps
The 5164G-001 keeps home time on the skeletonized central hour hand and shows local time with the solid central hour hand. Separate day/night apertures identify whether it is day or night in each zone, and the local date is coupled to local time. To adapt the display after a time-zone change, the wearer uses pushers on the left case flank to move the solid local-hour hand forward or backward by one hour at a time.
In its 2024 Watches and Wonders release, Patek Philippe says this adjustment does not affect the watch’s rate accuracy. That describes the effect of moving the local-hour hand; it is not an independent accuracy measurement of an individual watch.

Overseas: second-zone function is listed, setting detail is not
Vacheron Constantin lists a second time zone, day/night display, date, hours, minutes and central seconds for the 7920V/210A-B334. Its cited product page does not provide the same level of operating detail as Patek Philippe’s release, so the documented comparison is about listed functions rather than a claim that the two setting mechanisms work alike.
Water resistance: 30 m versus 150 m on these references
The official product pages state 30 m water resistance for the Aquanaut 5164G-001 and 150 m for the steel Overseas 7920V/210A-B334. This is a substantial difference in the published ratings, but the figures alone do not establish which water activities are appropriate. Follow the manufacturer’s guidance for the specific watch rather than inferring an activity recommendation from the rating alone. These values should not be generalized to every model in either collection.

Case size, thickness and power reserve
The cases are close in diameter: 40.8 mm for the Aquanaut and 41 mm for the Overseas. The listed thicknesses differ more: 10.2 mm for the Patek and 12 mm for the Vacheron. Those dimensions describe the cases, not how either watch will fit a particular wrist.
The manufacturer-listed power reserve is 35–45 hours for the 5164G-001 and 60 hours for the 7920V/210A-B334. Both movements are self-winding and listed at 4 Hz. The longer stated reserve belongs to the Overseas in this comparison; the specifications do not establish comparative accuracy or real-world running time.

Strap and bracelet flexibility
The Aquanaut reference is listed with an integrated blue-gray composite strap. The Overseas comes on a steel bracelet with an interchangeable system, and Vacheron’s cited page lists additional rubber and grained calfskin leather straps. That gives the Overseas page-documented alternatives for changing the watch’s wearing configuration; it does not by itself establish comfort, durability or how easily a change can be made.
