About this watch

The Audemars Piguet Royal Oak Offshore 25721 Chronograph is a masterpiece of luxury watchmaking, combining impeccable engineering with undeniable style. Its stainless steel construction and eye-catching blue dial make it perfect for both casual and formal settings. The octagonal bezel, secured with eight hexagonal screws, adds a touch of industrial charm to the overall aesthetic. At its core lies the Audemars Piguet caliber AP 2126 / 2840, a self-winding automatic mechanism featuring a chronograph complication. This movement showcases incredible craftsmanship and has a rich history, being introduced in the mid-80s as a collaboration with Jaeger-LeCoultre's JLC 889 base. With 33 jewels and a power reserve of 45 hours, this movement is designed to keep ticking, even when you're not wearing it. The chronograph function is incredibly user-friendly, allowing you to measure elapsed time with precision. Whether timing your runs or measuring cooking times, this watch has you covered. Its durability is also impressive, with a stainless steel case that's robust yet lightweight and a water resistance of up to 100 meters.
