Technical glossary
Black Bay 41 vs 58 vs 54: three different lug widths
Tudor Black Bay 41 → 22mm lugs. Black Bay 58 → 20mm. Black Bay 54 → 20mm (with tighter bracelet width than the 58). The finder above distinguishes automatically, but if you order from catalogue verify 22 for the 41 and 20 for the 58/54 — it's among the most frequent mix-ups I see at the bench. Standard 1.8mm pin across the Black Bay sport line.
Pelagos: titanium + 22mm + specific bracelet
Pelagos 25600TN and 25600TB → 22mm, but with titanium lugs: the standard 1.8mm steel pin works, but for material consistency you'd switch to a titanium pin (softer, handle carefully when fitting). Pelagos 39 → 21mm. Pelagos FXD is locked: spring bars fixed for life, not replaceable without Tudor intervention. For those I don't sell bars — I only sell straps with compatible passes.
Vintage Tudor 7900-7928: the reference trap
On pre-1968 Tudor Submariners (ref. 7900-7928 with small crown) lug width is 20mm but lugs are cone-style — they need specific spring bars with sleeve at effective 19.5mm. On Submariners 7016, 9411, 76100 → closed 20mm standard lugs. On modern Heritage (ref. 79320, 79220) → 22mm with drilled lugs replicated from the historical reference. When in doubt, send me the reference plus a side case photo: the trap shows up often.

Frequent questions
Black Bay 41 vs 58 vs 54: which lug width?
Black Bay 41 and 41 GMT: 22mm. Black Bay 58 and 58 GMT: 20mm. Black Bay 54 (2023 vintage-inspired): 20mm. Pelagos 42 is 22mm but with curved bar, not straight. Never assume 22mm across all Tudor — the 58 and 54 are precise 20mm.
Titanium Pelagos: dedicated or universal spring bars?
Pelagos has specific curved spring bars (follows case profile). Straight 22mm universal works but leaves a small visible gap at attachment point. For clean fit you need curved 22mm — Curved section of catalog.
Vintage Tudor Submariner 7928: same as Rolex 5512?
Same Oyster case, same 20mm drilled lug. Vintage Rolex Sub drilled spring bars work perfectly on Tudor Submariner 7928, 7900, 9411/0. 2.0mm pin recommended for thick leather (Rolex cone-lug era).
