Vacheron Constantin Overseas chronograph

The Vacheron Constantin Overseas chronograph 5520V/210A-B148 is a steel chronograph with a 42.5 mm case. The case measures 12.67 mm thick. A sapphire crystal covers the blue dial, which shows luminous hands and indices along with a date aperture. Inside is the self-winding calibre 5200, carrying the Genevian Seal and offering 52 hours of power reserve. Alongside the chronograph, the movement also drives a small seconds display, and the display back shows the finishing on the oscillating weight. The steel bracelet closes with a folding clasp in steel. Water resistance sits at 150 metres, courtesy of the case construction.
