HAMILTON BRACELET & CLASP CODES

Hamilton bracelet codes

Modern Hamilton bracelet clasps typically feature the Hamilton 'H' logo and are often deployant-style clasps with the brand name or logo on the outer surface. The quality and design of the clasp generally correspond to the model line, with higher-end models like the Jazzmaster series typically featuring more refined clasp designs than entry-level Khaki Field models.

Vintage Hamilton watches were commonly sold on leather straps or with bracelets from third-party manufacturers, so original bracelet clasps from the American era are relatively uncommon. When present, vintage Hamilton bracelets may carry markings from manufacturers such as JB Champion or Kreisler. The bracelet or strap on a vintage Hamilton is frequently a replacement and is generally not used as a primary authentication factor.

What to Look For

Hamilton bracelets and clasps often carry model numbers, material codes, and date stamps. Check the inside of the clasp, the end links, and the underside of individual links. Codes may be engraved, stamped, or laser-etched depending on the era and model.

Understanding the Codes

Bracelet codes serve several purposes: they identify the specific bracelet model for ordering replacements, indicate the material composition (stainless steel, titanium, gold, etc.), and sometimes include a date code that reveals when the bracelet was made. This date may differ from the watch head production date if the bracelet was replaced or if the brand manufactured components at different times.
