The replica royal oak 15407OR is the rose gold double balance wheel skeleton. Same Cal. 3132 as the steel version, same 41mm case diameter, same openworked dial — but in 18K rose gold, which changes everything about how the watch reads on the wrist. The movement bridges pick up a pink gold tone that carries through the entire face. Rose gold is denser than steel, so you feel the additional weight immediately. The 45-hour power reserve keeps it running through a full day and most of the next without attention.
Rose Gold Skeleton Character
On an openworked watch, the case material affects more than just the exterior. Because the dial is essentially the movement itself, the colour temperature of the case influences how the bridges and plates read visually. On the 15407OR, the rose gold case throws warm light into the movement cavity, giving the entire face a cohesive monochromatic warmth that the steel version does not have.
The bridges themselves are hand-finished with bevelled edges and alternating surfaces of circular graining and Geneva stripes. Under magnification, you can trace each component from the mainspring barrel through the gear train to both balance wheels. The replica royal oak 15407OR shows the same Cal. 3132 architecture as the newer 26515OR, but in the original double balance wheel format that AP introduced for this reference family.

Weight and Wrist Presence
18K rose gold has a density of approximately 15.2 g/cm³ compared to steel at 7.9. On a 41mm integrated bracelet watch, that translates to noticeable weight on the wrist. Some people prefer it — the heft confirms the watch is there. Others find it too much for daily wear. The openworked movement offsets this slightly by removing material from the dial side, but the case, bezel and bracelet still carry the bulk of the mass.
The bracelet uses the same link architecture as every other Royal Oak — alternating polished and brushed surfaces on a three-row pattern that tapers from 24mm to the clasp. In rose gold, the polished centre links catch light more aggressively than steel. Over time, rose gold develops a patina that softens the contrast between brushed and polished sections.
