Vacheron Constantin Brings Platinum and Copper Tones to the Overseas Ultra-Thin

Vacheron Constantin has given the Overseas a notably refined new expression, pairing the collection’s travel-ready character with the restraint of an ultra-thin platinum case.

Unveiled at Watches and Wonders 2026, the Overseas Self-Winding Ultra-Thin introduces a 39.5 mm platinum format to the collection for the first time, matched with a satin-finished dial in warm coppery tones.

It’s a sports watch in function, but the execution is closer to quiet precision than visual muscle.

At a glance

Platinum gives the Overseas a more discreet edge

The Overseas has long occupied a particular place among integrated-bracelet sports watches, balancing practical versatility with the finishing language of traditional Geneva watchmaking.

Here, that balance is sharpened by the use of platinum, a material that brings weight and presence without needing to announce itself loudly.

The case measures 39.5 mm across, a size that should sit comfortably between formal restraint and contemporary sports-watch proportions.

At just 7.35 mm thick, the watch keeps the profile slim enough to slide under a cuff, which is still one of the great practical pleasures of an ultra-thin automatic.

The copper-toned dial is a smart counterpoint to the cool density of the platinum case.

Its subtle satin finish avoids the obvious flash of a high-gloss treatment, while white gold hands and hour markers keep the presentation crisp.

Blue Super-LumiNova on the hands and markers adds the functional note expected from the Overseas family, without disturbing the watch’s more composed character.

Caliber 2550 is the real story inside

The headline refinement is not only external.

Inside the watch is Vacheron Constantin’s new Caliber 2550, an in-house automatic movement developed over seven years.

Rather than adapting the historic Caliber 1120, the Maison has created a new architecture for this ultra-thin movement.

That distinction matters, because ultra-thin watchmaking has been part of Vacheron Constantin’s identity for decades, reaching back to milestones such as the Caliber 1003 of 1955.

The Caliber 2550 runs at 3 Hz and is designed with daily use in mind, rather than existing purely as a technical showcase.

A platinum micro-rotor handles automatic winding, preserving the slender construction while keeping the movement visually and mechanically refined.

The double inverted barrel is another important detail, giving the watch an 80-hour power reserve that feels especially useful in a slim self-winding piece.

As with the watch as a whole, the movement is certified by the Geneva Hallmark, the Poinçon de Genève, which covers both technical and finishing standards.

The Overseas strap system keeps it practical

One of the strongest everyday advantages of the modern Overseas line is its interchangeable strap system.

This model continues that idea, allowing the owner to move between a platinum link bracelet, alligator leather and rubber straps in seconds.

That flexibility suits the personality of the watch particularly well.

On the platinum bracelet, it reads as a precious-metal sports watch with real presence.

On leather or rubber, the same case and dial can feel more relaxed, which broadens how often the watch can realistically be worn.

For collectors, that matters as much as the movement specification.

Details & Specifications

The Overseas Self-Winding Ultra-Thin is clearly aimed at collectors who value the tension between sportiness and finesse, especially when that finesse is expressed through movement architecture rather than ornament alone.

With platinum, a restrained copper-toned dial and a serious new ultra-thin caliber, it feels like one of the more considered evolutions of the Overseas idea.
