First, and the simplest of the new references, is the 15407BA.OO.1220BA.01 (come on AP, give us nicer reference numbers to work with). It’s a yellow gold edition measuring 41mm in diameter with the classic octagonal shape. That’s paired with an anthracite grey openworked dial showcasing the double balance wheel movement, calibre 3132. It’s effectively a non-diamond bezel version of the existing rainbow bezel edition. Ultimately meaning it’s a little less flash and ostentatious (as far a full gold watch can be) putting the emphasis on the haute horological movement.
The last of the trio is reference 15416CE.OO.1225CE.02, which has the same rose gold dial as the steel model above. However, instead of steel the case is made from black ceramic giving it a more contemporary aesthetic. It also highlights the fact the visible screws are made from gold, which is also true of the steel model.
Zooming out from the specific Royal Oak Double Balance Wheel Openworked references for a moment, they are all stunning piece of haute horology. The calibre 3132 dates back to the original launch in 2016 and has a 45-hour power reserve. The highlight is undoubtedly the titular double balance wheel, which features two hairsprings on the same axis and that oscillate in synchrony in order to improve precision and stability.
