When Vacheron Constantin introduced the Overseas Dual Time reference 7900V/110A-B334 at Dubai Watch Week in 2017, it marked a turning point for the collection. Full production began in 2018, bringing the brand’s first dual time complication in stainless steel, driven by a new in-house caliber and presented with a lacquered blue dial that collectors immediately noticed as a future classic.
The Overseas Dual Time 7900V/110A-B334 is the kind of piece you want with you every time you pack a bag and head to the airport. The deep blue dial immediately sets the tone, reminding you that this is a watch built for travel but rooted in Vacheron Constantin’s long history of fine watchmaking. For collectors who value practicality and history, the VC Overseas Dual Time feels like the perfect bridge between the two worlds.
So, let’s explore how this model came to life, what makes it stand out in the Overseas lineup, and why it deserves a spot in any collection focused on travel-ready luxury.
The Evolution of the Dual Time in the Overseas Lineup
The Overseas collection has been Vacheron Constantin’s entry into the luxury sports watch category since 1996. Its roots trace back to the 222, a steel model from 1977 with an integrated bracelet and distinctive notched bezel. That watch showed Vacheron could build something more versatile than a dress piece, while still applying the fine case detailing and movement finishing that had long defined the brand.
The first generation (1996–2004) introduced the Overseas design language: bold cases, strong water resistance, and a focus on everyday wear. The second generation (2004–2016) brought sharper lines and a bracelet with half Maltese cross links. In 2006, the collection gained its first Dual Time reference 47450, which used a small subdial for home time and extra indicators for day and night. While functional, it often felt crowded and wasn’t the easiest to read quickly.
Things changed in 2016 with the third generation. Vacheron gave the Overseas a modern update: in-house calibers across the range, a quick-release strap system, and a Geneva Seal applied to the entire watch, not just the movement. The result was a collection that could finally compete head-on with other steel sports watches in quality and practicality.
In 2017, the Overseas Dual Time reference 7900V/110A-B334 was introduced. This model simplified the way the second time zone was displayed. Instead of a small subdial, it placed a second hour hand at the center of the dial. The hand can even be tucked directly under the main hour hand when it isn’t needed, leaving the dial looking clean and uncluttered. Combined with its lacquered blue dial and stainless steel case, this Dual Time became the watch that finally made the complication easy to use while traveling.
History sets the stage, but the real personality of the 7900V/110A-B334 comes through in its case and bracelet – let’s explore those next.
The Steel Frame That Defines the Overseas Dual Time
The Overseas Dual Time reference 7900V/110A-B334 comes in a 41 mm stainless steel case, with a thickness of 12.8 mm. On paper, these numbers sound modest, but the tonneau-style profile and angular lugs give the watch more wrist presence than the dimensions suggest. The case carries a mix of finishes – brushed across most surfaces with high-polished edges running along the sides. That same high-polish carries through to the sides of the bracelet links, while the top and underside stay brushed.
Front and back are protected by scratch-resistant sapphire crystals. The rear crystal reveals the movement through a transparent exhibition caseback, while the front crystal gives a clear view of the blue lacquered dial. Surrounding it all is the notched bezel, a signature feature of the Overseas collection. Here the bezel is shaped like the Maltese cross: its top surface is high-polished, and the recessed areas between the notches are vertically brushed.
Water resistance is rated at 150 meters, supported by two screw-down crowns – one at 3 o’clock for time setting and one at 4 o’clock dedicated to the Dual Time function. These crowns help secure the case against moisture while keeping the watch practical for travel.
The bracelet design is just as much a hallmark of the Overseas as the bezel. It is entirely brushed on its broad surfaces, with high-polished bevels, and the center links echo the Maltese cross motif. Every link is removable, so sizing is precise. Built into the clasp are two small 1.5 mm extensions on each side, giving a total of 3 mm of easy adjustment without tools. The clasp itself is a push-button double-deployant, secure but simple to operate, with the Vacheron Constantin name inside.
Inside the presentation box, Vacheron includes two additional straps (blue rubber and blue alligator leather) each supplied with its own stainless steel folding clasp. The brand’s patented quick-release system makes switching between the bracelet, rubber, and leather effortless, taking only seconds. It’s a setup that allows the watch to adapt easily from travel days to formal evenings without feeling like three separate watches.
After looking at the case and strap, the next step is the dial, the part that brings the second time zone to the forefront.
The Blue Lacquered Dial That Defines This Piece
The lacquered blue dial of the Overseas Dual Time reference 7900V/110A-B334 is one of its defining traits. Under changing light, it shifts from deep navy to brighter shades of blue, giving the watch a lively character on the wrist.
Applied white gold baton indices mark the hours, each filled with Super-LumiNova for clear visibility in the dark. To aid orientation, the markers at 3, 9, and 12 o’clock are slightly thicker than the rest. A slim central seconds hand sweeps across the dial, while a chapter ring with 60-minute graduations frames the outer edge, keeping timing precise.
At the center, two hour hands display home and local time. The second time zone hand is tipped with a triangular pointer, making it easy to spot. When not needed, it can be tucked directly beneath the main hour hand, leaving the dial clean.
The functional elements are laid out with balance. At 6 o’clock sits a pointer-date subdial, where a hand with a crescent tip circles the dates 1 through 31. At 9 o’clock, an AM/PM indicator uses a small triangular marker to show day or night for the home time. Together, these keep the display practical for travelers without feeling overloaded.
Printed just below 12 o’clock is the “Vacheron Constantin Genève” signature, standing out crisply against the lacquered blue surface and grounding the design in the brand’s history.
The clarity on the dial wouldn’t be possible without the engine behind it, and that’s where the movement comes in.
The Mechanics Behind the Dual Time Display
Driving the Overseas Dual Time reference 7900V/110A-B334 is Vacheron Constantin’s in-house caliber 5110DT, an automatic movement built on the caliber 5100 that debuted in 2016. By adding a dual-time module, Vacheron created a caliber that balances practicality with fine watchmaking. It beats at 4 Hz (28,800 vibrations per hour), uses 37 jewels, and is made up of 234 components. When fully wound, it delivers a 60-hour power reserve, giving travelers plenty of cushion between wears.
The movement’s functions are designed to be intuitive. The crown at 3 o’clock controls most of the settings: it can wind the watch, move the local hour hand forward or backward in one-hour jumps, and automatically shift the date when crossing midnight. The home time hand and its AM/PM indicator remain fixed, keeping reference time accurate. The second crown, placed at 4 o’clock, is a dedicated pusher that quickly corrects the date. This separation of controls makes the watch easy to operate compared with many dual-time or GMT models.
On the dial side, the movement’s thoughtful design ensures the second time zone hand can be hidden directly beneath the main hour hand when not in use. Combined with the AM/PM indicator and pointer-date subdial, the layout stays legible without clutter – an achievement not every travel watch manages.
With a caliber this functional and beautifully finished, it is natural to ask how the watch actually feels once worn.
How the Overseas Dual Time Wears in Real Life
On paper, the Overseas Dual Time measures 41 mm in diameter and 12.8 mm thick, but the way the case flows into the bracelet makes it feel more substantial. The broad stance across the wrist gives the impression of a slightly larger watch, yet the curved lugs and sloping bezel keep it sitting flat and comfortable.
The steel bracelet spreads the weight evenly, with the clasp’s small extension links allowing for quick adjustments that come in handy as the wrist shifts during the day. Swapping to the rubber strap lightens the feel and leans into the sporty side of the watch, while the leather strap gives it a more polished character. Each option changes not just the comfort, but also the look of the lacquered blue dial – it appears brighter and more casual on rubber, deeper and dressier on leather, and balanced on steel.
This ability to adapt is what makes the Overseas Dual Time easy to live with. So, whether worn for travel, the office, or relaxed weekends, it has the appeal of a luxury sports watch while remaining versatile enough to suit different settings.
Having explored the wearing experience, here’s a clear breakdown of the essential specifications.
