Audemars Piguet's reference 26574ST was introduced in 2015, and is extremely sought after by modern collectors.

Quite revolutionary from the get-go, at 41mm the timepiece is sure to mark its presence on the wrist, however mainly in diameter and not in thickness. That is because Audemars Piguet developed and introduced for this model the all-new self-winding cal. 5134 which is based on the famous extra slim cal.2120 found on the original Royal Oak A series. Whilst the movement is indeed larger, fitting in the larger case, it remains relatively slim for greater ease of wear. Furthermore, the new caliber offered an additional complication, a 52-week calendar indication.

The white lettering and indices, when contrasting against the brushed blued grand-tapisserie dial render the timepiece extremely legible. The stunning moon phase indication, with its photorealistic moon and lapis starry sky, sits both symmetrically and comfortably at 6 o'clock adding the final touch of marvelous to this remarkable timepiece.

In barely worn condition, with its deep blue grand tapisserie, this watch exudes elegance and finesse, appealing to the most discerning of collectors.
