When purchasing a Rolex through ACbuy's proxy service, movement performance verification becomes paramount. ACbuy implements a rigorous spreadsheet-based QC system to meticulously track every critical parameter of your watch's movement before delivery.

Precision Timekeeping Verification

ACbuy technicians record daily rate variations across five positions in the monitoring spreadsheet, comparing results against COSC chronometer standards (-4/+6 sec/day). This datalogging continues throughout the 7-day evaluation period.

Dial-up position deviation ▸ ±1.2s (avg)
Crown-left position deviation ▸ ±1.8s (avg)
Temperature-compensated results included

Power Reserve Validation

The QC spreadsheet documents two full wind-to-stop cycles using specialized torque measuring tools, ensuring every caliber meets:

Minimum 70-hour reserve for 32XX movements
≥48 hours for discontinued models
Mainspring tension consistency metrics

End-to-End Process Visibility

Buyers access their model-specific spreadsheet via secure portal, containing:

QC Phase	Documented Metrics
Initial Examination	Time-stamped intake photos, anti-magnetic shielding test
Day 3 Evaluation	Amplitude consistency (270-310°), beat error (≤0.6ms)
Final Certification	Technician credentials, calibration certificates

Why This Matters

"ACbuy's spreadsheet QC goes beyond standard authentication by providing empirical movement performance data normally only available to watchmakers. This mitigates the risk of receiving a genuine Rolex with subpar timekeeping." - Horological QC Specialist

Your QA Assurance Protocol

Review timegrapher screenshots in your spreadsheet (pages 3-7)
Verify technician credential hashes match ACbuy's registry
Cross-reference results with official Rolex tolerances for your caliber
Approve shipment only after all cells show PASS
