270 years since its founding, 2025 was one of the biggest years in Vacheron Constantin’s long and revered history.
There were anniversary editions of the Traditionnelle and Patrimony, a 1m tall, 250kg La Quête du Temps automaton clock, and a host of technically outrageous creations that demonstrated just how far Vacheron Constantin is (and has long been) willing to push the boundaries of mechanical watchmaking.
But if you thought 2026 would be a rare opportunity for the Geneva manufacture to rest on its gilded laurels, you’d be surely mistaken. Just 30 years after the Overseas became a contemporary classic, Vacheron Constantin still has plenty to celebrate; this time with an anniversary release that combines one of the Maison's most recognisable sports-watch designs and one of its most enduring technical specialities.

Limited to just 200 pieces, the new Vacheron Constantin Overseas Perpetual Calendar Ultra-Thin arrives in an 18K white-gold case and a striking new azure dial colour, a classic combination and a collection first, that immediately delivers rare daily wearability to a timepiece that retails for $219,000.
A decade on from the first look at Vacheron Constantin’s Overseas (and a debut for the collection’s first azure dial), today’s reference boasts a lighter, softer shade of blue than its predecessors. It’s arguably the most immediately noticeable departure from the Overseas Perpetual Calendar Ultra-Thin we've seen before.
For the brand, this reimagined blue is designed to complement the gentle shimmer of the white gold case without flooding the dial with too much saturated colour. It also adds a unique depth against the collection’s inherent calendar indications and applied hour markers.
And at 41.5mm across, it sits in my favourite sweet spot for any sports watch: enough presence so you don’t lose it under the cuff, but framed in a way that it won’t swallow your wrist.
But it’s under the proverbial hood where this 2026 release truly shines: a near six-decade continuation of an ultra-thin movement architecture that ranks among the defining achievements of 20th-century automatic watchmaking.
Sitting at just 4.05mm thick, Vacheron Constantin’s Calibre 1120 QP/1 is so absurdly thin that the title “Ultra-Thin” almost doesn’t do it justice. Especially when you consider what’s packed inside: an automatic winding system and a full perpetual calendar tracking the day, date, month, and leap-year cycle, alongside a moon-phase display; all within a movement barely thicker than a stack of five credit cards.
The watch is also supplied with two additional rubber straps, one white and one denim blue, which can be swapped without tools thanks to Vacheron's quick-change system.
It’s fair to say that the Overseas has always occupied that sweet spot between sports watch and high horology, dragging the watch category that came to define the ‘70s with undeniable classics like the 222. But the addition of a perpetual calendar tends to pull most watches firmly towards the latter.
Here, Vacheron Constantin has managed to preserve enough of the collection's original travelling spirit, while packing one of traditional watchmaking's more demanding complications into a case scarcely thicker than some time-only watches.
Perhaps that's the most fitting way to follow up a 270th anniversary and a year spent showing the rest of the market how technically ambitious a modern Maison can (and should) be. By releasing something you'd actually want to wear in perpetuity. A no-brainer for our latest Watch of the Week.
