Housed in an 18-carat pink gold case measuring 41mm in diameter with 50m water resistance, this Royal Oak chronograph presents its signature octagonal architecture in one of horology's most refined precious metals. The dial carries the "Bleu nuit nuage 50" designation, rendered with the Grande Tapisserie pattern and matching "Bleu nuit nuage 50" chronograph counters, complemented by pink gold applied hour-markers and Royal Oak hands finished with a luminescent coating.
Powering the watch is a selfwinding calibre measuring 32mm in diameter and 6.8mm thick, oscillating at 4 Hz (28,800 vph) with a 70-hour power reserve. The movement comprises 381 parts and 40 jewels, and delivers flyback chronograph functionality alongside hours, minutes, small seconds, and date indications.
The watch is worn on a blue alligator strap secured by an 18-carat pink gold AP folding clasp, maintaining the warm tonal harmony of the pink gold case throughout the ensemble. Reference 26240OR.OO.D315CR.02 represents a considered combination of the Royal Oak's geometric design language with the added complexity of a flyback chronograph.
