Reference 26574BA.OO.1220BA.01 presents the Royal Oak in an all-18k yellow gold construction, extending from the 41mm case and bezel through to the bracelet, which secures with a fold clasp. A sapphire crystal protects the blue dial beneath, while a screw-down crown contributes to the watch's 20-metre water resistance.
Driving the perpetual calendar display is an automatic movement, offering a self-winding mechanism that tracks date, day, month, and leap year without requiring manual correction at the turn of each month. The blue dial serves as the canvas for these indications, lending the piece a distinctly refined character.
This Royal Oak represents one of the more demanding executions within the lineup, combining precious metal throughout with one of horology's most admired complications. Case dimensions are 41mm, reference 26574BA.OO.1220BA.01.
