The Overseas Self-Winding 41mm is one of Vacheron Constantin's signature luxury sports watches, distinguished by its sculpted stainless steel case, distinctive six-sided bezel and integrated bracelet inspired by the Maltese Cross. This version features a deep blue dial with applied luminous hour markers and hands, together with a date aperture at 3 o'clock. The combination of the blue dial and polished and satin-finished stainless steel creates a versatile appearance that works equally well for refined and casual occasions. At its heart is the Manufacture Calibre 5100, an automatic movement operating at 28,800 vibrations per hour and offering approximately 60 hours of power reserve. The movement is visible through the transparent sapphire crystal caseback and carries the Hallmark of Geneva.
