- Caliber inspection — case-back opened on tool bench, verify caliber code, rotor finish, trademark stamping, and timegrapher accuracy (rate, beat error, amplitude)
- Documentation verification — for 2020+ pieces verify Rolex Code 50 via digital system; for earlier pieces verify font, size, and AD stamp
- Summary judgment — combine all data, write detailed opinion with confidence level (high / medium / low) before quoting price
