Housed in a 37mm stainless steel case with 50 metres of water resistance, this Royal Oak carries the hallmark octagonal bezel design that has defined the collection for decades. The grey dial features the "Grande Tapisserie" pattern, white gold applied hour-markers, and Royal Oak hands with a luminescent coating, all secured behind the case and paired with a stainless steel bracelet fastened by an AP folding clasp.
Power comes from a selfwinding calibre measuring 26.2mm in diameter and 3.9mm in thickness, beating at 4 Hz (28,800 vph) with 29 jewels across 188 components. A 60-hour power reserve keeps the watch running through extended periods off the wrist, while the movement delivers hours, minutes, centre seconds, and date display.
Reference 15550ST.OO.1356ST.07 represents a refined, mid-sized expression of the Royal Oak lineage, combining the collection's distinctive stainless steel construction with a versatile grey dial that transitions effortlessly from casual to formal wear.
