The Vacheron Constantin Overseas watch took 10 months to build a high-quality stainless steel case with a diameter of 41mm, a sapphire crystal back, 7750 to 5200 automatic winding mechanism, a swing frequency of 28800 times per hour, and a stainless steel buckle. Waterproof to 150 meters. The last thing that must be appreciated is the brand-new "replaceable strap system". The new Overseas only needs to toggle a small lever between the strap and the lugs to replace the strap, and each one can choose steel strap, The belt is truly a 1:1 replica
