About the Overseas family
The Overseas was introduced in 1996 as the successor to the 222 of 1977, Vacheron Constantin's integrated-bracelet sports watch. Its bezel takes its shape from the Maltese cross. The third generation, launched in 2016 with ref. 4500V, introduced a system for changing between bracelet and straps without tools, and those watches come with extra straps in the box.
The line covers time-and-date models, chronographs, dual time, world time, ultra-thin models with caliber 1120 and perpetual calendars with the 1120 QP, in steel, pink gold, white gold and platinum. Dealers check the full reference, dial colour, the extra straps and the papers, and look for polishing on the bezel.
