How this valuation works
The live band is computed from in-stock listings matched to this reference across our tracked merchants (asking prices, not offers). The auction band is from documented, primary-sourced results in the Record Ledger corpus. The trend is the brand cohort's movement on the repeat-listing Price Index — tracked since 2026-05-30, honestly labeled, never extrapolated. Cite as “MostExpensiveWatches Valuation”.
