Source note
Spec backfill (2026-08-08, round 7): sibling to id=71 (Black Bay One 39) but verified independently rather than carried over, per the task's caution -- tudorwatch.com's own page title (indexed in search results as "TUDOR Black Bay One 41 watch - 41mm steel case, Steel bracelet - m79680-0001"; direct fetch blocked, same 403/Akamai issue as ids 69/70 above), cross-checked against Jomashop, ShopSimon, Springer's, and a second independent aggregate search, all agreeing: stainless steel case (brushed and polished), anthracite dial, scratch-resistant sapphire crystal, stainless steel bracelet with folding clasp, 100m water resistance, automatic movement via Tudor Calibre MT5601 (COSC) with 70h power reserve. Notably this uses caliber MT5601, NOT the MT5602 already on file for the 39mm sibling (id=71) -- a genuine, expected difference between the two case sizes (same family, different specific caliber), not a data-entry inconsistency; confirms the task's caution to verify the 41mm case independently rather than assume it shares every spec with the 39mm. jewel_count not found in any source checked -- left NULL. Unresolved: jewel_count, bezel_type, year_introduced, complications.
