Audemars Piguet Royal Oak 5402 Stainless Steel Black Dial

The Audemars Piguet Royal Oak 5402 A Series is a foundational piece in watchmaking, widely credited with inventing the luxury sports watch category upon its 1972 debut. Designed by Gérald Genta, this 39mm stainless steel timepiece broke new ground by blending high-end horology with an industrial aesthetic and a steel case, a radical concept at the time. Collectors particularly seek out the A Series as it represents the initial 2,000 pieces ever made.
