LONGINES BRACELET & CLASP CODES

Longines bracelet codes

Longines bracelet clasps typically feature the winged hourglass logo, and modern clasps are commonly butterfly deployant designs with branded buckles. The clasp quality and finishing generally reflect Longines' position as a mid-to-upper-range Swiss watch brand. Polished and brushed stainless steel clasps are the most common, though gold-tone and two-tone options are available on certain models.

Vintage Longines watches were often sold on leather straps with simple Longines-branded buckles, and finding original vintage bracelets in good condition can be difficult. As with other brands, clasps and bracelets are commonly replaced over a watch's lifetime, so they should be assessed in context with the overall watch rather than used as sole authentication criteria.

What to Look For

Longines 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.

#02

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.
