This refers to a Patek Philippe 5712A Nautilus with a blue dial that has undergone a complete, top‑tier modification. A “full mod” typically includes:
- CNC original‑data case with correct “parrot beak” profile
- High‑quality aftermarket or genuine dial, hands, and moon phase
- Custom non‑indexed 240 movement with weighted balance, gilt engraving, and a solid 22K or 18K gold rotor
- Upgraded bracelet and clasp to match original specs
This is the ultimate expression of the 5712A – every detail pushed to the max for maximum authenticity and performance.
