Secondary / used

Asking $480–$680

Suggested buy ~$460 · sell ~$600

full set · single_source

Real gap: couldn't confirm the actual sold price behind the WatchUSeek paywall. Range is wider than ideal given that.

Sources: One pre-owned listing citing this exact reference at $479.99 (dial described as 'Pearl White' by the reseller, likely the same as catalog's 'Silver' -- inconsistent labeling, not treated as a different watch). A WatchUSeek SOLD thread exists for this exact reference but the sold price itself was paywalled/inaccessible.

Source note

Case thickness (11.3mm) and lug-to-lug (47.3mm) from a reference-specific WatchDetails.com listing, but only via search snippet -- the page itself failed to load directly (cert error), so this is unverified against the primary source. Treat as provisional until independently confirmed. Spec backfill (2026-08-06): Certina official site + WatchBase. Case thickness corrected 11.3mm -> 11.7mm -- the black-dial sibling (same 807.11 case family) turned up a more reliable source giving 11.7mm; case thickness shouldn't differ by dial color, so applying the better-sourced figure here too. Unresolved: jewel_count, bezel_type, year_introduced, clasp_type.
