AP/Audemars Piguet Royal Oak series 26331OR chronograph uses the same BD1 7750 chronograph

AP/Audemars Piguet Royal Oak series 26331OR chronograph uses the same BD1 7750 chronograph movement as the original (6-digit small seconds). The 316 stainless steel case is brushed and partially polished to show a delicate and tough uniqueness. Temperament, rough and elegant 41mm dial, full of strength, super luminous display, can read the time in any environment. Sanjie exquisitely recommends men's multi-functional mechanical watch SJ to carefully create ultra-realistic photo shooting for you.
