Customer‑ordered latest version AP15500ST blue dial “Steel King” modification ✈️
- CNC original‑data developed steel case, bracelet tapered / thinner
- Top‑tier aftermarket dial, hands, and date wheel developed from original data
- Powered by a non‑indexed 4302 integrated movement – weighted balance, gilt engraving, 18K gold rotor
This is a customer‑commissioned Audemars Piguet 15500ST in blue, the iconic “Steel King” Royal Oak. The case and bracelet are CNC‑machined from original factory data, with the bracelet specifically made tapered and thinner – an important detail that improves comfort and replicates the genuine’s elegant taper. The dial, hands, and date wheel are top‑tier aftermarket parts based on original data, ensuring the signature blue “Grande Tapisserie” pattern and correct printing. The movement is a non‑indexed 4302 integrated caliber – a true free‑sprung balance with adjustable weighted screws, proper gilt engraving on the bridges, and a solid 18K gold rotor (not plated). This movement replicates the functions and aesthetics of the genuine AP 4302.
This build represents the highest level of custom 15500ST available: a precision‑machined steel case with a correctly tapered bracelet, a high‑quality aftermarket dial, and a movement with serious upgrades (non‑indexed, gold rotor). It is aimed at collectors who want the ultimate Royal Oak “Steel King” experience without paying the factory premium.
A customer‑ordered AP 15500ST blue – steel case with a properly thin tapered bracelet, top‑tier dial, and a movement with a real 18K gold rotor and non‑indexed balance. This is as good as custom steel Royal Oaks get. Ready to impress.
