The Audemars Piguet Royal Oak Perpetual Calendar, reference 26598BC.ZZ.1220BC.01, is a 2024 men’s watch with a 41mm white gold case and a deep red dial. The dial has a square tapisserie pattern and applied baton hour markers instead of numerals. Three subdials show the day of the week, the month with the leap-year indicator, and the date. A blue moon-phase display sits at 6 o’clock, and a week-number scale runs around the outer edge.
The octagonal bezel is set with baguette-cut diamonds, and the integrated white gold bracelet matches the case. A perpetual calendar tracks month lengths and leap years on its own, so you never reset the date after a short month. The automatic movement winds from the motion of your wrist. Sapphire crystal covers the dial and guards it against scratches.
Condition is very good, and it is delivered with its original box and papers. White gold Royal Oak models tend to hold their value.
