The upgraded version of the Vacheron Constantin Overseas watch V3 in white case and rose gold took 12 months to create. It has a fine stainless steel case with a diameter of 41mm, a sapphire crystal case back, a 5200 automatic winding mechanism, and a swing frequency of 28,800 times per hour. , stainless steel buckle, waterproof to 150 meters. The last thing I must appreciate is the new "interchangeable strap system". The new Overseas only needs to move a small lever between the strap and the lug to replace the strap. , each one can choose steel straps, tapes, belts, 3 straps per watch, truly 1:1 replica.
