Nicknamed “Ice Blue,” this version pairs a frosted pale blue Grande Tapisserie dial with darker blue subdials, a contrast that sets it apart from the original blue Royal Oak Perpetual Calendar. It suits the collector who already owns the obvious pieces and wants one that quietly says more. Anyone who buys watches because they love them, rather than because a list told them to, will understand it on sight.

Presents itself in mint condition with little to no signs of wear. Under light, the frosted blue dial shifts between looking like brushed metal and fresh snow. Brushed surfaces meet mirror-polished bevels across the octagonal case and bracelet, so the watch moves between matte and gloss as the wrist turns. At six o’clock, a lacquered moon sits against a small field of stars and tends to hold the eye longer than expected.

Functions include hours, minutes, perpetual calendar, day, date, month, leap year, week of the year, and astronomical moon phase. Pulling the crown sets the time, while the self-winding movement keeps the calendar running on its own. Recessed correctors in the side of the case let the supplied stylus adjust the day, date, month, and moon, and the calendar already accounts for short months and leap years, so it will not need correcting until 2100. A slim central hand points to the week of the year on the outer ring.

Comes as full set, double-boxed with international warranty card, warranty booklet, and instructional manual.

No longer in production now that a newer model has replaced it, this reference closes out a chapter of the Royal Oak, the steel sports watch Gérald Genta designed for its 1972 debut. Athletes and musicians have worn the Royal Oak for decades, though this complicated version lands hardest with collectors who recognize it across a room. If it speaks to you, it probably already feels like yours.
