Tudor bracelet clasps commonly feature the Tudor shield logo on the outer surface, and modern clasps often include the Tudor name as well. Vintage Tudor watches frequently used Rolex-manufactured clasps bearing Rolex coronet stamps or codes, which is consistent with the historical arrangement between the brands. Modern Tudor clasps are proprietary designs, often featuring robust folding mechanisms with micro-adjustment holes or the T-fit clasp system introduced on recent models.
The quality and style of the clasp can sometimes provide clues about the watch's era and authenticity. Modern Tudor clasps on the Black Bay and Pelagos lines are typically solid, well-finished pieces with clean engravings. Vintage clasps from the Rolex-supplied era may carry stamped codes on the inside that can be cross-referenced with known references. As bracelets and clasps are commonly replaced components, their markings should be evaluated alongside the case, dial, and movement.
