To celebrate three decades of the Overseas collection, Vacheron Constantin presents the Overseas Perpetual Calendar Ultra-Thin model featuring a new sky-blue dial and a white gold case—a combination never seen before.

Released in a limited edition of 200 pieces, this watch is powered by the Manufacture Calibre 1120 QP/1, an automatic movement that ranks among the thinnest in its category, measuring just 4.05 mm in thickness. Furthermore, it remains accurate until the year 2100 and incorporates a moon-phase display featuring a starry sky and golden moons.

For the first time in the collection, it features a sky-blue lacquered dial with a sunburst satin finish and a tone-on-tone moon disc, housed in an 18K white gold case. A sapphire crystal caseback allows the movement to be admired.

The sub-dials feature a guilloché finish, alongside an 18K white gold moon-phase disc that matches the dial color. The 18K white gold hands and applied hour markers are enhanced with blue Super-LumiNova.

True to the Overseas spirit, the watch is customizable thanks to three easily interchangeable straps—two in rubber and one in 18K white gold—along with an interchangeable 18K white gold buckle.
