Authorized dealer
Asking $4,675–$4,900
Suggested ceiling ~$4,675
IMPORTANT NAMING CAVEAT (see existing open flag on this watch): this reference (79830RB) is documented everywhere checked, including this catalog's own flag, as the Black Bay GMT 'Pepsi' (red/blue bezel) -- NOT a genuine 'Root Beer' colorway (Tudor's real Root Beer GMT is a different ref, M79833MN, steel-and-gold). Researched and logged as stored (79830RB) since that's the catalog row needing pricing, but this data describes the Pepsi watch -- don't treat it as Root Beer pricing if the row gets corrected later. No discount applied -- new AD stock at stated retail, not a negotiated price.
Secondary / used
Asking $3,500–$4,200
Suggested ceiling ~$3,220
Same Pepsi-not-Root-Beer caveat as the AD pass above. Chrono24's full raw range is wider ($2,744-5,239); used the $3,500-4,200 band WatchCharts describes as most examples' actual selling range, not the extremes. Tier assumed full_set (typical for Chrono24 dealer stock at this price point) but not individually confirmed per listing -- single_source reflects that uncertainty, not just source count. 8% discount-from-asking applied per this project's standard convention.
