AUDEMARS PIGUET Cobra Ref. 5403 – 1970

This Audemars Piguet Ref. 5403, nicknamed the “Cobra” for its fluid, scale-like integrated bracelet, is a striking example of AP’s 1970s design language. Crafted from solid 18k yellow gold and measuring 35mm, it houses the ultra-thin automatic caliber 2121—one of the most refined movements of its era. The dial is the true centerpiece: a rare and vivid surface that shimmers between tones of falcon’s eye, tiger’s eye, and deep wood grain, creating a warm, organic feel under changing light. Diamond hour markers punctuate the dial with subtle brilliance, adding just the right amount of contrast and elegance. Likely dating from the mid-1970s, this Cobra is a rare blend of technical finesse and bold design. A refined yet unmistakable statement from one of watchmaking’s great houses.
