The Audemars Piguet Royal Oak Double Balance Wheel Openworked 15407ST.OO.1220ST.01 puts the calibre at the centre of the design. Instead of a solid tapisserie dial, the reference uses an openworked slate-grey display with exposed bridges and two superimposed balance wheels. It is a technically focused Royal Oak for someone who values visible mechanical detail.
The Royal Oak case remains 41 mm, but the dial opening transforms its character. The octagonal bezel still frames the display, while the geometry of the movement creates a second layer of depth beneath the sapphire crystal. Pink-gold applied markers and Royal Oak hands ensure that the time remains readable against the open architecture.

A skeleton watch has nowhere to hide. The bridges should appear defined rather than flat, the wheel surfaces should be finished consistently, and the movement should look clean through the front and display back. Dial legibility also matters: the hands and markers need to remain visible when the background is busy. The openworked display is not a printed pattern, so it should reward close inspection under different lighting angles.
RO TIME provides available QC images so these details can be reviewed before dispatch. Buyers comparing this reference with a solid-dial Royal Oak should consider whether they value understated legibility or visible mechanical depth more.
We inspect bezel screws, bracelet finishing, movement presentation, date alignment and clasp operation. The watch ships with discreet tracked packaging; read the shipping and customs guide for delivery information.
