Audemars Piguet Royal Oak Chronograph Steel — Khaki Green Grande Tapisserie 41mm | Ref. 26240ST.OO.1320ST.08

Among the Royal Oak Chronograph references of recent years, the khaki green dial variant of the 41 mm steel model has attracted some of the most fervent collector attention — a convergence of the format's most desirable attributes: generous proportions, the iconic steel bracelet, and a dial colour that shifts between deep olive and brilliant emerald depending on lighting conditions. Gerald Genta's architectural language — the octagonal bezel, the eight exposed screws, the seamlessly integrated bracelet — is rendered here in brushed and polished stainless steel, its contrasting surfaces as rigorously executed as ever.

The Calibre 4401 flyback chronograph movement powers the watch, its column-wheel mechanism operating at 28,800 vph with a power reserve of approximately 70 hours — exceptional for an integrated chronograph of this complexity. The green Grande Tapisserie dial extends its guillochage across matching subdials at three, six, and nine, housing a running seconds counter, a 30-minute totaliser, and a 12-hour register. Luminescent Royal Oak hands and applied hour-markers ensure legibility in all conditions, while the date window at three sits neatly within the overall composition. The transparent sapphire caseback reveals the movement in all its alternating-finish splendour.

On the integrated steel bracelet with AP folding clasp, the 41 mm case wears with the confidence of a tool watch and the pedigree of a collector's grail. Water resistant to 50 metres, presented with box and papers, Ref. 26240ST.OO.1320ST.08 in khaki green is the benchmark against which all modern steel sport chronographs are ultimately measured.
