About this watch

The Audemars Piguet Royal Oak Perpetual Calendar 41 Ceramic / Slate stands as a testament to the brand's legacy of innovation and elegance. At its heart lies the exceptional Audemars Piguet caliber AP 5134, an automatic movement that redefines the boundaries of watchmaking. With its extra-thin design, suspended barrel, and frequency of 19,800 vibrations per hour, this caliber is designed for precision. The movement's gears are meticulously crafted, offering a seamless experience as it tracks hours, minutes, and calendar features like date, day, leap year, and month indicators. The moon phase indicator, laser microstructured on an aventurine base, adds an ethereal quality to the watch. The combination of titanium and ceramic makes this timepiece durable, lightweight, and scratch-resistant, while the slate grey dial provides a captivating backdrop for its features. Measuring 41mm in diameter and just 9.5mm in height, the Royal Oak Perpetual Calendar is perfectly sized for various wrists. Its unique shape and open case back offer a glimpse into the intricate workings of the movement, allowing wearers to appreciate the craftsmanship involved. With a water resistance of 20 meters, this watch is suitable for everyday wear, but not designed for deep-sea diving. The Royal Oak Perpetual Calendar 41 Ceramic / Slate is an investment that combines innovation and elegance in a way that few can rival.
