8F Vacheron Constantin Overseas watch upgraded version V2. It took 10 months to create a fine stainless steel case with a diameter of 41mm, a sapphire crystal back, an automatic winding mechanism, a swing frequency of 28,800 times per hour, and a stainless steel watch. Buckle, waterproof 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. Optional steel belts and belts can truly achieve 1:1 reproduction.
