The upgraded version of VACHERON CONSTANTIN overseas watch takes 10 months to build a high-quality fine steel case with a diameter of 41mm, a sapphire crystal mirror back, a 7750 to 5200 automatic chain feeding machine, a swing frequency of 28800 times / hour, a fine steel buckle and a waterproof of 150m. Finally, we must appreciate the new "replaceable strap system". The new overseas only needs to move a small paddle between the strap and the ear to replace the strap. Each strap can be selected with steel belt and belt to truly achieve 1:1 reproduction
