This is an ultra‑exclusive custom Audemars Piguet Royal Oak 15412BC, dubbed a “Super VIP hidden model.” The watch features a steel case and bracelet CNC‑machined to original factory data, ensuring precise dimensions and finish. The bezel is set with CVD synthetic sapphires – a vibrant blue gemstone that offers excellent brilliance and color consistency, mimicking natural sapphires at a lower cost. The movement is an original‑data developed integrated 3132 caliber, which has been heavily customized: it includes a non‑indexed weighted balance (true free‑sprung regulation) and a skeletonized double balance wheel – a complex, high‑end feature that creates a stunning visual effect of twin oscillating balances.
This build targets collectors who want a truly unique Royal Oak that goes beyond standard customizations. The combination of a diamond‑like sapphire bezel, a steel case, and a skeleton movement with twin balances is rare and dramatic. It’s a conversation piece that blends technical innovation with bold aesthetics.
A VIP‑level AP 15412BC with a blue sapphire bezel, steel case, and a skeleton movement featuring twin balances. Not for the faint of heart – a true showpiece.
