The Anatomy of Kakobuy's QC Spreadsheet System

Unlike traditional verification methods, Kakobuy's dynamic spreadsheet provides:

Pro Tip: Cross-reference your spreadsheet's 24-hour amplitude readings with COSC's 270°-330° requirement—the clearest indicator of movement health.

How Buyers Actively Participate in QC Oversight

  1. Upon order confirmation, receive your unique spreadsheet link
  2. Monitor progressive test completion through color-coded cell updates (gray → yellow → green)
  3. Validate timing results against the 60-hour power reserve benchmark
  4. Use embedded @mentions to request additional crown position tests if needed

"After seeing my Submariner's spreadsheet show consistent +1.2s/day at 288° amplitude across 7 temperatures, I had more confidence than AD paperwork could ever provide." - Marc W. (Geneva)

When Spreadsheet Data Demands Action

Should any parameter fall outside Rolex's Superlative Chronometer specifications:

Metric Acceptable Range Automatic Retest Trigger
Daily Rate -2/+2 sec ±3 sec variance
Power Reserve >70 hours <70 hours

Utilize spreadsheet-integrated buttons to:

  • Request secondary regulation (with video documentation)
  • Download full torque calibration reports
  • Initiate movement replacement protocols
