Royal Oak Selfwinding / 37 mm

Alongside new chronographs in 38mm and 41mm sizes, Audemars Piguet is refreshing the Royal Oak collection, on the occasion of its fiftieth anniversary, with new automatic three-hand and date models in a 37mm diameter. While staying true to the original 1972 design, these new releases introduce subtle refinements to the case, dial and bracelet. Equipped with new calibres, most feature the specially created “50 Years” rotor. Calibre 5900 powering hours, minutes, seconds and date makes its debut on these 37mm models. Slimmer by 0.36mm than its predecessor, Calibre 3120, it also beats at a higher frequency of 4Hz (as opposed to 3Hz). The Tapisserie guilloché dial remains the unmistakable signature of the Royal Oak collection.
