Source note
Spec backfill (2026-08-08, round 7): tudorwatch.com's own page title (indexed in search results as "TUDOR 1926 watch - 39mm steel case, Black dial - M91550-0002" and, separately, "...39mm steel case, Steel bracelet - m91550-0002") -- a direct fetch was blocked (tudorwatch.com returns 403/Akamai bot-protection for both WebFetch and a direct curl with a browser user-agent, same as round 6's experience with this site). Cross-verified via a direct WatchMaxx product-page fetch (Case Material "Stainless Steel" polished finish, Crystal "Scratch Resistant Sapphire", Dial Color "Black", movement "Tudor Calibre T601" ~38h reserve, Water Resistance "100 Meters", Bracelet "Polished Stainless Steel", Clasp "Brushed and Polished Stainless Steel Folding clasp", Case Thickness "9.20mm"), consistent with cdpeacock.com, Fink's, Betteridge, Mayors, and H.L. Gross listings. jewel_count=25 found via one aggregate search summary only (not independently fetched/confirmed on a specific retailer page) -- lower confidence than the rest of this row's fields, but a plausible, unremarkable figure for this caliber family, left unfilled rather than stated with the same confidence as the rest (see jewel_count left out of this UPDATE). bezel_type similarly single-sourced ("Fixed/smooth") -- left out for the same reason. Unresolved: jewel_count, bezel_type, year_introduced, watch_type.
