The 1970s were the golden age of the hardstone dial, when the great houses set slices of lapis lazuli, malachite, and onyx into precious cases, and Audemars Piguet's Cobra was among the most elegant canvases for that trend. Named for the flexible woven bracelet that coils like a snake, the model paired slim movements with jewelry-grade craftsmanship. This white gold example reaches for pure opulence, its vivid lapis dial framed by a full pavé of diamonds.

Measuring 25 by 29 millimeters, the cushion-shaped white gold case is edged by a lavish pavé of brilliant-cut diamonds that completely surround the dial. At its heart, a slice of deep blue lapis lazuli glows with natural depth, flecked with gold pyrite, marked only by the Audemars Piguet signature and slim diamond-set hands. A hand-wound movement powers the display. The finely woven white gold mesh bracelet flows from the case like liquid, unmistakably vintage.
