In 2018 Audemars Piguet introduced a Royal Oak with a vibrant green coloured dial, made specially for the Hong Kong market and retailed by Unique Timepieces.

Limited to 50 pieces only, the reference 26606ST represents the timeless collaboration between Audemars Piguet and Unique Timepieces and features an automatic caliber 5134 with a perpetual calendar. The movement consists of 374 parts and proudly showcases through the sapphire crystal display back.

The present watch exhibits a rare complication as well, with a yellow hand indicating the week of the year on the edge of the dial, redefining what a perpetual calendar should be. The moon phases is crafted from aventurine, its dark blue contrasting magnificently with the rest of the deep green dial as if looking upon the stars from the midnight forest. The watch is furthermore offered in brand new condition and still retains with its original factory sticker.
