The APS factory's Audemars Piguet 15500 all ceramic style has arrived, combining ceramic materials with the complex functions of the cal.4302 all-in-one machine, becoming a model of craftsmanship and innovation. It not only continues the classic aesthetics of the Royal Oak tree, but also breaks through the limitations of traditional materials, making it a benchmark for modern high-end watchmaking The advantages of ceramic materials are high hardness and scratch resistance: made of precision ceramics (such as zirconia), the hardness far exceeds stainless steel, making it less prone to scratches during daily wear and maintaining long-lasting luster. Lightweight and comfortable to wear: Compared to metal materials, it is lighter and reduces the burden on the wrist, making it suitable for long-term wear. Anti allergy and corrosion resistance: Ceramics have stable chemical properties, are not prone to skin sensitivity, and are resistant to sweat and corrosion. Unique texture: The surface is finely polished or matte treated, presenting a deep luster or low-key texture, with a total of three color options available: black, white, and rare blue The integrated structure of the case and strap design: The APS case seamlessly connects with the strap, continuing the iconic octagonal bezel of the Royal Oak and the "Tapisserie" checkered dial, while the ceramic material gives a modern feel. Complex process: APS adopts ceramic sintering forming, which is extremely difficult and requires precise control of temperature and pressure, resulting in low yield and highlighting technical strength. Detail processing: The strap links are chamfered and polished, with soft edges that fit snugly on the wrist; The thickness of the watch case is about 10.5 millimeters, balancing complex craftsmanship and wearing comfort.
