full set · single_source

This exact reference was already a real, verified repeat-buy target pre-ADR-0004 ($350 buy / $550 sell, verified 2026-08 per prior research) -- this fresh pass lands close to that ($370/$550), a reasonable cross-check rather than a contradiction. Genuinely wide spread across sources for this reference, more so than most; confidence held to single_source rather than cross_verified given how much individual listings vary.

Sources: Chrono24 ($482-850 across several listings), eBay ($773 asking, one hacking-movement variant sold ~July 2024, price unconfirmed), WatchUSeek/Reddit ($249-280 range, lower/older listings). Wide spread across sources -- excluded the $850 and sub-$280 extremes as outliers.

Source note

Cross-verified via eBay/WatchCharts/EveryWatch/WatchUSeek listings for this exact reference. Confirmed discontinued (H644555 is the current replacement reference) -- exact discontinuation year not found, left year_discontinued NULL despite being discontinued (a real schema gap: NULL normally reads as "still in production"). dial_color left NULL deliberately -- this reference covers multiple dial colors (champagne, black), matching Tony's own "flexible on dial color" note. strap_type/strap_material left NULL -- both leather-strap and steel-bracelet configs exist under this reference, ambiguous which applies. lug_to_lug_mm and case_thickness_mm left NULL -- case thickness sources conflict (11mm vs 12mm), no reliable lug-to-lug found. bezel_type/clasp_type unresolved, consistent with this catalog's existing pattern for field watches. Reconfirmed (2026-08-08, round 8): re-checked as part of a dial_color/strap_type backfill pass. Found further corroboration of a steel-bracelet configuration (EveryWatch dealer listing 9780084; an independent OEM parts retailer, watchbandexpert.com, sells a steel replacement bracelet specifically fit for this ref family) and a distinct Champagne-dial listing (EveryWatch 13412214) alongside the Black-dial listings -- same two-axis ambiguity already documented above, not new information strong enough to pick one configuration. Left dial_color/strap_type NULL, no change. Reconfirmed 2026-08-08 (backfill round 8): dial_color and strap_type remain correctly NULL -- prior research (eBay/WatchCharts/EveryWatch/WatchUSeek) already established this reference covers multiple dial colors (champagne, black) and both leather-strap and steel-bracelet configs exist under it, matching Tonys own noted flexibility on dial color for this piece. No new source found that narrows it to one configuration, so left as-is rather than pick arbitrarily.
