Timex bracelet clasps, when present, commonly display the Timex name or logo. The brand has used a variety of bracelet and strap types over the years, from expansion bands popular in the mid-20th century to modern leather, NATO, and stainless steel bracelet options. Vintage Timex expansion bracelets were often produced by third-party manufacturers such as Speidel and may carry those manufacturers' markings rather than Timex branding.
Given that Timex watches are frequently sold with interchangeable straps and that the brand actively promotes strap-changing as a feature (particularly with their Quick-Release spring bars), the bracelet or strap on a Timex watch is often not a reliable indicator of originality or authenticity.
