The Vacheron Constantin Overseas Dual Time ref. 7900V/110A-B546 is a 41 mm stainless-steel travel watch built around the third-generation Overseas design. Its black dial combines central local time with a second time-zone hand, a day/night indication and a pointer date at 6 o’clock, giving the watch useful travel functionality while preserving the balanced, integrated-sports-watch character of the collection. The 12.8 mm case is water resistant to 150 metres and is paired with Vacheron Constantin’s interchangeable bracelet system.
Inside is the self-winding calibre 5110 DT, a 4 Hz manufacture movement with approximately 60 hours of power reserve. The movement carries the Hallmark of Geneva and is visible through the sapphire caseback, where its 22K gold oscillating weight reinforces the travel-oriented identity of the Overseas line.
Reference 7900V/110A-B546 is distinguished by its black-dial configuration and represents the earlier 7900V generation of the Overseas Dual Time. Its combination of steel construction, second-time-zone functionality, strong water resistance and interchangeable bracelet and strap system makes it particularly relevant to buyers seeking a versatile high-end sports watch with genuine travel utility.
