Since its introduction in the early 1970s, the Royal Oak model has garnered widespread acclaim for its timeless design, range of complications, and innovative use of materials. Among them is the present reference 25730ST, a dual-time collection with a smaller 36mm diameter case compared to the original “Jumbo”. However, this timepiece showcases a striking and distinctive blue dial, which has become an icon in its own right. The fascination with the sky and its colors led French painter Yves Klein to develop a vibrant shade of ultramarine blue, which he believed captured the essence of space. This color, known as "International Klein Blue (IKB)", became a central theme in Klein's paintings. When Audemars Piguet introduced a similar vibrant blue color in their watches, collectors quickly dubbed it "Yves Klein". The present timepiece features the iconic petite tapisserie blue dial, complemented by a lacquered texture at the second time zone at 6 o'clock, a power reserve indicator at 9 o'clock, and a date display at 3 o'clock, creating a captivating contrast. Offered in excellent overall condition, the current watch comes complete with its full set of accessories. It represents a highly sought-after neo-vintage timepiece that should not be overlooked by collectors and enthusiasts alike.
