Doesn’t the diving watch count with a unidirectional rotating bezel? (See the right column.) Audemars Piguet knows that you do n’t dive every day, so it is hidden in the case: the detent mechanism that controls the unidirectional rotating inner ring is connected to the crown at 10 o’clock Turn the crown off before turning the device). In this way, this watch still inherits the classic, elegant appearance of the Royal Oak series, and has the functionality of diving. This watch is equipped with an Audemars Piguet Cal. 3120 automatic movement. To ensure accuracy, the core components of the movement use an adjustable weight balance that vibrates 21,600 times per hour. Eight small weights make the adjustment of the movement more accurate and stable, and can maintain stability for a long time. In addition, it is also resistant to compression, shock and magnetism, and the iconic hexagonal screws on the surface make you feel as if it is solid.
