Measuring 41mm in stainless steel, this Royal Oak houses a selfwinding calibre with a flying tourbillon complication that rotates openly within the rhodium-toned openworked dial. White gold applied hour-markers and Royal Oak hands finished with luminescent coating stand out against the slate grey inner bezel, while the open architecture of the movement becomes the centrepiece of the watch face.
The selfwinding movement spans 31.5mm in diameter and a slender 6.2mm in thickness, running at 3 Hz (21,600 vph) with 27 jewels across 271 individual parts. A 65-hour power reserve ensures extended autonomy, and the watch carries a water resistance rating of 50 metres.
A stainless steel bracelet with an AP folding clasp completes the piece, echoing the case material for a cohesive look. Reference 26735ST.OO.1320ST.02 represents one of the more technically ambitious expressions within the Royal Oak family.
