A solid eighteen carat pink gold and diamond set Audemars Piguet Carnegie. The Audemars Piguet Carnegie is a slim, curved tonneau dress watch from the 1990s, defined by its softly arched case and clean, time only layout. The reference was launched in precious metals with simple straps, or in more jewellery-led executions with diamond-set cases and dials, such as this example. Many examples were fitted with compact hand-wound movements, with quartz variants also produced across the line.

Introduced in the mid 1990s, the Carnegie arrived at a moment when Audemars Piguet was expanding its design language beyond the Royal Oak, leaning into elegant case shapes that still felt contemporary. The name is a deliberate nod to Andrew Carnegie, tying the collection to the era’s industrial optimism and philanthropy, and to Audemars Piguet’s own balance of tradition and innovation. The case profile is the key: curved for comfort, refined in proportion, and unmistakably of its period, while also a nod to classic watch case design.

The watch, reference 77156OR/Z/0009/01, was made as part of a limited series of models on the theme of these stunning jewellery watches in the 1990's. They came in a mix of metals and designs, but all were similar in their elegance. The pink gold case is set with seventy eight brilliant cut diamonds chasing the frame of the watch. They are, as one would expect from AP, top quality I/F colour top Wesselton stones. They frame the watch beautifully, without being overwhelming. 

The dial in this example is one of the finest they made. The factory produced dial itself is a hand cut piece of pink mother of pearl. The hour markers are a mix of round brilliant diamonds and rubies, with a fine pair of pink gold dauphine hands that pass elegantly over it. The base of the dial is printed "Swiss Made", and is all original, damage free and not reprinted. 

The watch is powered by an AP mechanical caliber 2046 movement that is working well, keeping perfect time. Hand-wound, two-hand shaped calibre designed for tonneau cases is an eighteen jewels, 21,600 vph (3 Hz), and around 42 hours of power reserve, with approximately 85 components. Launched in the mid-1990s shaped references including this Carnegie model, and later in other tonneau and jewellery-focused models

The condition of the watch is superb throughout. There is a full set of hallmarks and Swiss control marks on the back of the watch. Along with the unique serial number stamped into the case back. The original AP stamped alligator band is present along with the eighteen carat original pink gold buckle, which is fully stamped with Swiss control marks, and AP marks. 

On the wrist, the Carnegie wears flatter than most rectangular watches, with a quiet presence that suits formal settings but does not feel delicate. It is a strong choice for collectors who want a distinctly 1990s Audemars Piguet that stays understated, with enough design character to stand apart from the usual round dress watch.

The watch is in perfect original and unpolished condition. It is keeping perfect time. The watch has its original papers.
