The 20-Point Condition Grading Matrix

Unlike traditional A/B/C grading systems, Superbuy's spreadsheet platform implements a hyper-detailed 20-level classification for pre-owned Rolex watches:

  • 90-100 points: Mint/NOS (new old stock)
  • 85-89 points: Near mint (hairline scratches)
  • 80-84 points: Excellent (visible wear)
  • 75-79 points: Very good (moderate polishing)
  • Below 75: Requires full disclosure

Each grade corresponds to specific criteria regarding case polishing, dial patina, bracelet stretch, and movement service history.

Integrated Document Verification

The spreadsheet automatically cross-references third-party authentication reports with:

  1. Macro photography of case engravings
  2. Movement serial number close-ups
  3. Lume plots condition under UV light

Machine learning algorithms analyze discrepancies between seller descriptions and verification images - triggering an automatic listing suspension

  • "Refinishing marks" appear in reports but omission on product page
  • Caseback tool marks suggest unauthorized access
  • Lume color mismatches production era

Smart Pricing Algorithm

Analyzing 18,000+ completed Rolex transactions, the spreadsheet revealed key market patterns:

Condition Premium Over 80-Grade Days to Sell
95-Grade 22-28% 17.2 avg
90-Grade 15-20% 24.6 avg
85-Grade Market Parity 41.3 avg

The "Condition-Premium Index" now directs procurement teams to:

  • Prioritize 87-93 grade pieces for fastest inventory turnover
  • Apply dynamic pricing - adjusting +1.5% weekly for stalled listings
  • Bundle 79-84 grade with warranty extensions

Cross-Platform Monitoring

Superbuy's spreadsheet syncs pricing data with:

  • Chrono24 condition benchmarks
  • Japanese auction house archives
  • Manufacturer service center lead times

This creates an industry-first self-correcting pricing model where Rolex Submariner 116610 LN valuations update hourly based on affiliated platforms' moving averages.

With Superbuy's trusted verification process clearly documented here, resellers gain quantified condition analysis previously only available to auction houses - while buyers receive bankable quality assurances they can truly invest in.
