Vacheron Constantin released the Overseas Perpetual Calendar Ultra-Thin this autumn to celebrate the anniversary of the Overseas collection. The limited-edition timepiece features a white gold case and a refined azure blue lacquered dial, combining a moon-phase display with a high-complication mechanical movement.
The new release marks three decades since the Swiss Manufacture first launched its Overseas collection in 1996. This anniversary model arrives as a limited run of 200 pieces, maintaining the collection’s signature utilitarian aesthetic—specifically the flat case and bezel secured with visible screws.
Calibre 1120 QP/1 and Ultra-Thin Engineering
Engineering a perpetual calendar into a slim profile is a technical challenge, yet the Overseas Perpetual Calendar Ultra-Thin achieves a case thickness of only 8.11mm. This compact housing contains the Calibre 1120 QP/1, a self-winding mechanical movement developed and manufactured entirely by Vacheron Constantin.
The movement powers a complex array of displays. These are complemented by a moon-phase display using a matching disc.
Azure Blue and White Gold Aesthetics
While Vacheron Constantin introduced azure blue to its repertoire in 2016, this model uses a new interpretation of the color. This specific lacquered dial is lighter and less saturated than previous versions, designed to shift subtly depending on the light.

- Case and Bracelet: A white gold case paired with a satin-finish white gold bracelet featuring links shaped like a half Maltese cross.
- Markers: 18-karat white-gold hour markers and hands, accented with blue Superluminova for visibility in low light.
- Strap Options: In addition to the metal bracelet, the watch can be fitted with denim blue or white rubber straps.
Evolution of the Overseas Collection Since 1996
The Overseas was not the brand’s first foray into sporty elegance; it followed the 222, which was launched in 1977 and sketched by designer Jorg Hysek. Along with the 1975 Chronomètre Royal, the 222 helped define the brand’s balance between casual sportiness and pared-back luxury.
| Year | Key Development |
|---|---|
| 2004 | Introduction of integrated bracelets with Maltese Cross-inspired links |
| 2016 | Launch of the third generation, featuring a tool-free quick-change strap system |
The current iteration’s quick-change system is a core part of the user experience, typically providing a set of three straps—leather, metal, and rubber—that the owner can swap without tools.
