Hands-On: The Vacheron Constantin Overseas Ultra-Thin 2500V

The new Vacheron Constantin Overseas Ultra-Thin 2500V is a release from the brand at this year’s Watches and Wonders that’s gotten quite a bit of chatter, deservedly so. After all, it is the brand’s thinnest-ever Overseas, thanks to a brand-new in-house movement developed over seven years, which means what I assume to be an ungodly amount of R&D dollars per millimeter shaved. It’s also come at a time when Vacheron seems to be really having a moment — the passion I saw amongst Vacheron collectors when I was in Miami last month for the opening of the brand’s largest U.S. boutique was very much an exciting sight to see. 

But is the final result worth all the effort? Very much so, if we take the new Overseas Ultra-Thin 2500V as an ultra-limited, ultra-expensive halo product to mark the development of this new caliber. This 2500V and the Overseas Dual-Time Cardinal Points released alongside it at Watches and Wonders are already seeing very strong demand, and I think that’s a sign of a good showing in Geneva.

To many collectors of Vacheron over the years, the previous ultra-thin, time-only Overseas 2000V might feel like it had just come out, but in fact, a decade has passed since its introduction. Coming in white gold, the case measured 40mm in diameter, with a thickness of 7.5mm. Inside was the Vacheron 1120 caliber, a version of the JLC caliber 920 that had found its way in many watches amongst the Holy Trinity of brands, thanks to its superlative of being the thinnest automatic movement with a full rotor, even to this day. Priced at $55,700 at launch in 2016, it was beautiful, expensive, and very hard to find.

And now in 2026, Vacheron’s new Overseas Ultra-Thin remains similar in theme: beautiful, expensive, and very rare. The 2000V was never a limited edition, but thanks to its boutique-only status and the small production run, the watch was not easy to get your hands on, even if you had the money. 

This new 2500V is very much limited by definition, produced in a run of 255 individually numbered pieces. But here, dimensions have been slightly reduced in both aspects, with a diameter that is now 39.5mm and a thickness shaved down to 7.35mm. These reductions on what was already an incredibly thin watch might not be the most perceptible, but what will be on the wrist is the weight, as this version of the 2500V (2500V / 210P-H028, if we’re being specific) is rendered entirely in platinum. Yes, that means that despite the lack of a prominent case height, the sheer density of this watch is something to behold.

The brilliance of platinum is paired with a bright salmon-lacquered dial. Modern Overseas dials are among the most captivating in the segment, with a lacquering process over a sunray-brushed dial that creates a shine that feels simultaneously smooth and metallic. Thanks to the lack of a date window on the new Overseas Ultra-Thin, dial symmetry is achieved quite well here, with long applied hour markers. I’ve said it before, but I really am not a big fan of salmon dials due to my skin tone. But this one is less salmon and more of a light orange copper, a nice shade in my opinion.

The long-overdue revival of the Ultra-Thin is really thanks to the final development of Vacheron’s own ultra-thin in-house automatic caliber to supersede the JLC-based movement found in the 2000V, and here we have the new caliber on full display through the 2500V’s sapphire caseback. Coming in at a svelte 2.4mm tall, this new Caliber 2550 is unabashedly modern in its specs. Evidently, the theme of platinum continues to the movement side, thanks to a micro-rotor. The density of platinum for the microrotor, paired with bidirectional winding, means a better winding efficiency for 80 hours of power reserve. 80 hours might not sound that impressive across the industry these days, but for a caliber of this size, it very much is. It’s achieved through the suspended double barrel, which stacks one barrel on top of the other despite the two barrels still operating in series and not in parallel.

Certified with the Poinçon de Genève (or Geneva seal), the caliber aesthetic and finishing feel very modern Vacheron, with a clean layout that features a good amount of anglage to go with the various other finishes like Côtes de Geneve, perlage, and snailing. The microrotor features the compass rose motif found on the full rotor of some other Overseas models.

On the platinum bracelet, the new Overseas Ultra-Thin creates cognitive dissonance, as your wrist cannot reconcile the sheer weight relative to the case. That’s a lot of words to say that this thing is shiny and heavy, and feels all the more extravagant because of it. In the opposite way that the new Cardinal Points Overseas series merges sportiness and luxury through the twist of light-grade 5 titanium, the 2500V pays homage to the old-fashioned way of feeling luxury on your wrist through sheer density. 

It’s no surprise that the bracelet is constructed incredibly well, though it’s reaffirmed here in this metal. And while I’ve always been on the fence about whether the modern generation of Overseas perhaps featured the Maltese cross motif a bit too frequently around the watch, on the bracelet, that motif is actually a way to show off the incredible finishing of the several polished facets on each link. Micro-adjust is very much present and well-integrated into the clasp for an easy fit.

But like all modern Overseas, you actually get two more straps—one in dark beige alligator leather, and a beige rubber strap. Naturally, these certainly lighten the load a bit, though they exaggerate the weight of the watch head. While alligator leather gives you that classic dress-watch feel (and hey, this one might actually qualify as one since it’s a two-hander!), there’s something about a slim, dressy Overseas paired with a rubber strap. While I’ve never owned an Overseas, I’d imagine you’d be able to take advantage of all these straps anywhere you take this watch, thanks to the incredibly intuitive quick-change system.

On the wrist, the watch is unsurprisingly a very unique experience. While it’s a thin watch, it’s not a small watch per se—39.5mm is still considerable for a two-handed watch that can be interpreted as dressy. And I’ve always been of the opinion that thinness actually exaggerates diameter, which means that the span is made more noticeable. But it’s a common trait amongst modern Overseas models. In my opinion, they all tend to wear a bit larger than the measurements would suggest. Regardless, the case sits wonderfully flush on the wrist.

It’s also at this point where we kind of need to compare it to two things that popped into my head while I was taking a closer look at this watch, Vacheron’s own 222, of course, and the new Patek Philippe 5610P, a similarly priced, thinner platinum two-hander with a micro-rotor movement. Both of these other two watches are smaller in diameter than the 2500V, and the difference is noticeable in the wearing experience. In this trio of watches, the only white-metal option accessible to those without six figures to spend on a watch will be the 222 in stainless steel, which offers compact dimensions (37mm x 7.95mm) and a much more affordable price ($34,700). Would most people be plenty thrilled with the 222? Certainly, and despite the current demand around it, it will still be much easier to obtain than the 2500V. But they speak to very different buyers here: the 222 offers a charm in its design that’s frozen in time, while the 2500V offers a no-holds-barred advancement in modern watchmaking. Perhaps a more suitable comparison will come if we ever see a 2500V in steel.

A more comparable fight is between the Vacheron 2500V and the Patek 5610P, which also debuted at Watches and Wonders, as part of the brand’s celebration of 50 years of the Nautilus. The 5610P is smaller in both diameter and thickness, at 38mm wide and 6.9mm tall. Having tried both on, the wearability win certainly goes to the Patek on my smaller wrist. But Patek uses a very old movement here—Caliber 240 was first introduced in 1977, and as such, Vacheron’s new Caliber 2550 shines. Slightly larger in diameter than Patek’s caliber, though a hair thinner at 2.4mm versus 2.53mm, the Cal. 2550 handily beats the specs of the 240 with that much longer power reserve (80 hours versus 48) as well as bidirectional winding versus unidirectional. Not to mention, the contemporary engineering of the Caliber 2550 presumably gives it an edge in durability and shock resistance.

Specs aside, the big advantage of the Nautilus, as well as its biggest disadvantage, is, well, that it’s a Nautilus. Yes, you are getting an icon of watch design in arguably some of its best proportions since the original, but at the same time, the Nautilus draws public attention in a very big way. The Overseas offers a much more niche experience, with a silhouette that’s immediately recognizable in horological circles but a lot quieter in situations where you’d want it to be. Plus, despite the 5610P being certainly impossible to obtain, the 255 pieces of the 2500V are a lot more exclusive than the 5610P’s 2000 pieces. If you’re a more discreet collector, the 2500V is the pick here, hands-down.

The Overseas Ultra-Thin 2500V, in this first iteration priced at a hearty $120,000, offers a maximalist execution of a clean two-hand design, ushering in a new generation of ultra-thin movement. And while the substantial price tag was talked about almost as much as the watch itself, I’m under the impression that most, if not all, of these will already be spoken for by the end of Watches and Wonders. But what’s certain is that this is just the beginning for the Cal. 2550, as it’s sure to be used for more iterations of the Overseas Ultra-Thin down the line (I can hope we’ll see a steel version one day). I’m also certain we’ll see this movement used for Vacheron’s future ultra-thin complications—that classic Cal. 1120, still in use in the Overseas Perpetual Calendar Ultra-Thin, after all. But in the meantime, the Overseas Ultra-Thin 2500V will serve wonderfully as the first chapter of this story.
