This 18K 5N pink gold watch elegantly combines Fine Watchmaking with a sporty aesthetic. At just 8.10 millimeters thick, it houses an ultra-slim perpetual calendar which will display the correct date until 2100. A moon phase with two gold moons, whose sky blends into the blue hue of the dial, complements the calendar. The watch can be personalized thanks to its system of three easily interchangeable straps – leather, rubber, and 18K 5N pink gold. Through its links, the bracelet subtly reveals the Maltese cross, a Vacheron Constantin icon.

The origins of sporty watchmaking

Designed to suit an active lifestyle, the first Overseas models were created in 1996. Powered by the spirit of travel and openness to the world, this remarkably technical collection soon became a touchstone for the Maison. Flowing, ergonomic lines, subtle light effects and delicate finishes place the Overseas models firmly within a timeless yet distinctly contemporary aesthetic universe.

One Of Not Many

Zaria Forman

American artist Zaria Forman testifies to the impact of changing landscapes. A committed and uncompromising explorer, she has become the new face of Vacheron Constantin's "One of Not Many“ campaign and embodies the Overseas collection alongside Cory Richards.


One watch, three faces

The Overseas collection features an interchangeable bracelet/strap system. This technical trick enables the straps to be changed entirely tool-free, thereby enabling Overseas watches to take on new looks to match the circumstances. Every watch in this collection is supplied with an integrated bracelet fitted with a folding clasp, a rubber strap for a sportier vibe, and a calfskin leather strap in the same shade, for more classic character.
