ZF factory creates a new ceramic art to create the ultimate black and white diving sports watch Audemars Piguet Royal Oak Offshore Series 15707 Series[Case] ​​42MM black and white ceramic is fired at high temperature and high pressure, with strong lines and fashionable colors, which is refreshing. The surface of the ceramic is brushed, making the appearance more tough and gorgeous, and continuing the consistent waterproof performance of the Royal Oak Offshore, ensuring reliability in diving sports. The diving timing display is a two-layer bezel inside the dial, which is controlled by the crown at 10 o'clock, and the crown at 3 o'clock controls the winding and adjustment time. Both are screw-in structures.[Dial] Decorated with the brand's traditional "Méga Tapisserie" super-large checkered pattern, and paired with luminous fluorescent hands, the inner rotating timing ring from 12 o'clock to 3 o'clock is also decorated with orange and blue display areas. This makes the watch easy to read and more fashionable and dynamic.[Movement] ZF's self-produced Calibre 3120 automatic movement has a diameter of 26.6 mm and a thickness of only 4.26 mm. The movement has a total of 280 parts, which can ensure sufficient power reserve.[Strap] The strap is made of rubber material that fits the wrist, with a titanium alloy pin buckle. When worn, the wrist feels light and has no sense of burden, which facilitates flexible wrist movement.ZF's masterpiece is a latecomer! Hard against all versions of the Royal Oak 15707 on the market.
