Royal Oak Selfwinding 37 (current gen)

The Audemars Piguet Royal Oak Selfwinding 37 reference 15550ST represents the current generation of the iconic 37 mm Royal Oak in stainless steel. Introduced in 2022, it carries forward the octagonal bezel, integrated bracelet, and Grande Tapisserie dial that have defined the line since Gerald Genta's original 1972 design. The reference is offered in blue, silver, and grey dial variants, each preserving the hallmark sunburst finishing that shifts subtly with the light.

The Royal Oak's 37 mm size has long served as a versatile middle ground within the collection, appealing to collectors who prefer a slightly more restrained case diameter without sacrificing any of the model's architectural presence. The 15550ST arrived in 2022 as a thorough update to its predecessor, bringing with it the in-house Calibre 5900 and a refined case execution that reflects Audemars Piguet's ongoing investment in the Royal Oak line. Its introduction coincided with a period of renewed collector enthusiasm for the Royal Oak across all sizes, cementing the 37 mm as a serious reference in its own right rather than a secondary option.
