Vacheron Constantin Overseas watch stainless steel case, diameter 41mm, sapphire crystal case back, 5100 self-winding movement, swing frequency 28800 times per hour, stainless steel buckle, waterproof 150 meters. The last thing that must be appreciated 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.
