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.

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.

Source note

tudorwatch.com, 2026-08-06 research pass -- MSRP not confirmed (range $4,925-5,825), left blank Spec backfill (2026-08-08, round 6): Monochrome Watches' spec coverage (200m/660ft water resistance, domed sapphire crystal, domed black dial) plus consistent agreement from Bob's Watches, SwissWatchExpo, Bernard Watch, Jomashop, Watch Limit, and Avi & Co on black dial for this exact reference (one single outlier -- Bob's Watches' product-page fetch returned "white" for dial color, contradicted by every other source checked including their own listing title elsewhere in search results, read as a scrape/description error, not followed). FLAGGING FOR TONY: this catalog row's variation is "Root Beer" (brown/gold bezel), but every source checked for reference 79830RB specifically -- without exception -- describes it as the "Pepsi" bezel (red/blue), not Root Beer. Tudor's actual Root Beer-bezel Black Bay GMT is a distinct steel-and-gold reference, M79833MN. Unlike the Shinola Harbor/Cardinal question on id=56 (resolved this round -- turned out not to be a real conflict), nothing found here resolves this one; it looks like a genuine reference/variation-name mismatch worth checking, possibly inherited from the original import. Not touching the variation or reference fields (out of scope for this spec-only pass) -- the three spec fields filled here (water_resistance_m, dial_color, crystal_type) are correct for reference 79830RB as literally stored, regardless of how the naming question resolves.
