Vacheron Constantin Celebrates 30 Years of the Overseas with an Ultra-Thin Perpetual Calendar in Azure

The Geneva manufacture unveils a 200-piece limited edition of the Overseas Perpetual Calendar Ultra-Thin, featuring a brand-new azure dial paired for the first time with a white gold case.

Thirty years after the introduction of the first Overseas in 1996, Vacheron Constantin has chosen to mark the anniversary of its sport-chic collection with a release that is both understated and technically demanding. The Geneva manufacture has just presented the Overseas Perpetual Calendar Ultra-Thin Azure Blue, a 200-piece limited edition that pairs, for the very first time in this collection, an 18-carat white gold case with an azure-lacquered dial.

It is precisely this color that first catches the eye. Vacheron Constantin introduced its deep, highly saturated Overseas blue during the collection's revamp in 2016. The new azure shade is distinctly different: lighter and less intense, it plays with shifting light thanks to multiple layers of lacquer and metallic pigments. The result evokes a clear sky or calm water rather than a traditional sports watch dial, a tone that aligns perfectly with the travel-inspired heritage the collection has claimed since its inception.

The new shade is not the only first for this reference. The combination of the azure dial and the white gold case had never been offered before on the Overseas, giving this anniversary edition an immediately recognizable distinction without Vacheron Constantin needing to alter the silhouette of a watch that now holds a central place in the brand's catalog. The case measures 41.5 mm in diameter and just 8.1 mm thick, a remarkably slim profile for a timepiece housing a full perpetual calendar. This achievement is made possible by the manufacture Calibre 1120 QP/1, a self-winding movement measuring just 4.05 mm in height.

This calibre, inheriting a long tradition of ultra-thin watchmaking at Vacheron Constantin, manages the entire perpetual calendar: date, day of the week, month, leap year indication, and moon phase. Comprising 276 components, the mechanism requires no calendar adjustment before the year 2100, when the Gregorian calendar deems the secular year to be a non-leap year. The sapphire caseback offers a clear view of the movement and its finishes.

The Overseas was born in 1996 as the heir to the Reference 222 designed in 1977, which itself established the aesthetic of the integrated-bracelet sports watch that the Geneva manufacture has progressively developed. The current collection, whose design architecture dates back to 2016, is recognizable by its flat case, fluted bezel, and integrated bracelet with links shaped like the Maltese cross. For this anniversary edition, Vacheron Constantin offers three strap options that can be swapped without tools: the white gold bracelet, as well as two rubber straps, one in white and the other in blue.

This new release comes during a particularly busy 2026 for the brand, which has already introduced seventeen new references across all collections, including eight in the Overseas line alone. It also arrives during a busy period for the global watch industry: the Grand Prix d'Horlogerie de Genève 2026 opens its international exhibition tour today, September 28, at the St. Regis in Mumbai, showcasing 84 nominated watches across 14 categories, before traveling to Bangkok, Geneva, and London. The awards ceremony is scheduled for November 7 at the Bâtiment des Forces Motrices in Geneva. While Vacheron Constantin is not among the nominees this year, the brand has not waited for the jury's verdict to demonstrate the vitality of its flagship collection.

The Overseas Perpetual Calendar Ultra-Thin Azure Blue will be available in a strictly limited edition of 200 pieces, distributed through the Vacheron Constantin boutique network. No retail price has been announced for the French market at this stage.
