The 26330OR.OO.D088CR.01 is the Royal Oak Day-Date in rose gold, nicknamed the "Owl" for the twin sub-dials at 9 and 3 o'clock that show the day of the week and the date. Instead of the aperture windows used on most Royal Oak calendar models, each display gets its own recessed, concentric-ringed register set into the black Grande Tapisserie dial. It runs the caliber 2325/2810, a dependable day-date module rather than a showpiece movement, and it was only in the catalog from 2011 to 2013.
Collectors drawn to a distinctive dial layout, who don't mind a leather strap in place of the usual integrated bracelet, are the audience for this one.
The "Owl" nickname started with the original Royal Oak Day-Date, reference 5572/25572, a 36mm model AP built from 1983 to 1998 with the same twin sub-dial layout. The modern 39mm reference 26330 revived the idea in 2011 and ran for only about two years before AP discontinued it, which is why surviving examples are uncommon today. The rose gold version, 26330OR.OO.D088CR.01, was fitted exclusively to a brown alligator strap; the same dial layout in steel (26330ST) rides on the Royal Oak's usual integrated bracelet, but AP never combined rose gold with a bracelet on this model.
Inside is the self-winding caliber 2325/2810: 31 jewels, 28,800 vph, 40-hour power reserve, built to drive the twin day and date registers rather than to be shown off through a display caseback.
Because this reference was only sold for about two years, few buyers have handled a confirmed-genuine example in person, so comparing against verified photos is the most useful check before buying. The twin sub-dial layout at 9 and 3 o'clock is specific to this model; a "Royal Oak Day-Date" offered with a single day/date aperture, or with the sub-dials in different positions, is not this reference. The rose gold case was never fitted with a metal bracelet, so any example offered on a bracelet is either a different reference or a modified watch.
Rose gold cases show fine scratches and polishing wear more readily than steel; check the case flanks under direct light for over-polishing that rounds the beveled edges, which is irreversible. The solid caseback means the movement can't be checked at a glance, so ask for service history on any example more than five years past its last documented service.
