Vacheron Constantin Overseas dual time

The Vacheron Constantin Overseas Dual Time, reference 7920V/210R-B965, is a GMT watch cased in rose gold at 41 mm. The case measures 12 mm thick and carries a sapphire crystal over a green dial with luminous hands and indices. Inside is the self-winding calibre 5110 DT/2, holding a 60-hour power reserve and bearing the Geneva Seal. Beyond the second time zone, the watch adds a date function, and the sapphire caseback lets the movement show through. Rose gold hands and hour-markers stand out against the sunburst green finish. The bracelet is rose gold as well, closed with a folding clasp in the same metal. Vacheron Constantin rates the case to 150 metres.
