Omega bracelet clasps typically feature the Omega name or logo prominently on the outer surface, and modern clasps often include the Omega symbol engraved or embossed on the fold-over plate. The brand has used several clasp designs over the decades, ranging from simple stamped clasps on vintage models to the more refined push-button deployant clasps found on contemporary pieces. Modern Seamaster and Speedmaster bracelets commonly feature adjustable clasps with micro-extension capabilities, and the Planet Ocean line often includes a diver's extension mechanism.
Vintage Omega bracelets, particularly those from the 1960s and 1970s, may carry reference numbers on the clasp or end links that correspond to specific bracelet models in Omega's catalog. These reference numbers can help verify originality, as specific bracelets were designed to pair with particular watch references. However, bracelets and clasps are commonly replaced components, so the presence of a non-original bracelet does not necessarily indicate a problem with the watch itself. Collectors often examine the bracelet's reference number, finishing quality, and Omega markings when evaluating whether a bracelet is original to the watch.
