Born in the 1970s and still relevant today, few sports watches are as timeless as the Royal Oak. This 41mm model is a delight to wear; the 15400ST superseded the previous 39mm version, endowing the Royal Oak with its modern dimensions. The proportions are indeed a key appeal of this 15400ST. The grand tapisserie dial, executed in blue with a sunburst finish, enhances its avant-garde wrist presence. With all the modern advantages and maintaining its faithful Genta design, this Royal Oak is perpetually a watch with the future in mind. Please note that this particular piece is a reference 15400ST.OO.1220ST.01 which indicate it came from the factory with a black dial, which has been replaced to the blue dial from a 15400ST.OO.1220ST.03.
