This Audemars Piguet Royal Oak series chronograph 26240ST uses a 41mm stainless steel case and a white Tapisserie dial, equipped with a flyback chronograph function and a sapphire glass mirror. Equipped with an imitation CAL.4401 automatic timing integrated movement, the thickness is consistent with the original. The button rebound feel and timing start-up feel are both at a high level, showing mechanical aesthetics and top craftsmanship. The overall weight and fine steel texture are very original, and it is a very rare super replica version with high precision on the market.
