Audemars Piguet Cobra - Blue Diamond Dial

Details

Integrated Perfection

This is a vintage Audemars Piguet Cobra Ref. 5403, crafted in the 1980s (B-series) from solid 18k white gold. Measuring 35mm including the crown, it is powered by a reliable automatic movement with a quickset date function at 3 o’clock. The watch is paired with its original integrated 18k white gold woven bracelet, measuring 7.25 inches with a micro-adjuster for precise fit.

Case, Dial & Bracelet

The elegant white gold case is seamlessly integrated into the woven-finish bracelet, a hallmark of Audemars Piguet’s craftsmanship in this era. The dial is a captivating deep blue with diamond-set hour markers, offering a perfect blend of refinement and sparkle. The dial shows some light speckling under close inspection, but overall remains vibrant and full of character. The bracelet is original, intact, and designed for comfort with its finely executed woven texture.

Rarity, Condition & Collectability

Known among collectors as the “Cobra,” this reference exemplifies Audemars Piguet’s bold yet elegant design language of the late 20th century. The combination of blue diamond dial, automatic movement, and fully integrated white gold bracelet is rarely encountered, making this piece highly collectible. Both the case and dial remain in untouched cosmetic condition, with all components — crown, dial, movement, and caseback — confirmed original. The watch keeps excellent time and is fully functional.

Timeless Appeal

This AP Cobra is more than a timepiece — it is a fusion of precious metal, attractive dial design, and technical mastery. Distinct yet versatile, it transitions effortlessly between refined formal wear and stylish daily use, embodying the understated elegance that defines Audemars Piguet’s vintage creations.

History

The Cobra is one of the most sinuous and distinctive watches in the Audemars Piguet dress catalog — a bracelet watch whose integrated 18-karat gold links undulate in a pattern that evokes, and earns, the name. Produced primarily in the late 1970s through the 1990s, the Cobra houses ultrathin manual-wind movements in cases ranging from 26mm to 35mm.

These are watches that rewarded you for being close to them: the bracelet articulation, the surface contrasts between polished and brushed gold, and the dial finishing are all things a photograph undersells. Reference 5403 in yellow gold and 4239BA with pave diamond dials represent the range from elegant everyday wear to full haute joaillerie. The Cobra is AP at its most purely luxurious — no sport pretense, no complications for their own sake.
