A 15400 built around the strap
The 15400OR.OO.D002CR.01 pairs the black Grande Tapisserie dial with a rose-gold-tone octagonal case and black rubber strap. That combination keeps the Royal Oak geometry visible while changing the way the watch sits in a daily rotation.
ZF uses a modified Calibre 3120 architecture with a unidirectional winding system. The practical tradeoff is a rotor sound that can be noticeable in a quiet room; the benefit is a familiar 15400 layout with a strap-led wearing experience and a dial texture that carries the design.
