- CNC original‑data developed 18K solid gold case and bracelet
- Powered by an upgraded genuine 1185 movement – correct thickness, correct functionality
- Original‑data developed top‑tier aftermarket dial, hands, and date wheel










This is a fresh custom AP 26331BA – the “BA” denotes yellow gold, and the green dial makes it a rare and striking combination. The case and bracelet are CNC‑machined 18K solid gold using original factory data, so the weight, hallmarks, and brushed/polished finish are authentic. The movement is a genuine 1185 caliber (the same base as AP‘s 2385), which has been upgraded – likely with improved finishing, regulation, or a gold rotor. Crucially, the seller states that the thickness and all functions match the genuine . The dial, hands, and date wheel are top‑tier aftermarket parts developed from original data, ensuring the green “Grande Tapisserie” pattern, gold markers, and date font are correct.
For collectors who want a full‑yellow‑gold Royal Oak chronograph with a rare green dial, this build delivers genuine movement reliability and solid gold construction at a fraction of the factory price. The green dial is highly sought after, and the use of a genuine 1185 movement makes this a top‑tier custom piece. In stock and ready to impress.
