CASIO BRACELET & CLASP CODES

Casio bracelet codes

Casio bracelet clasps typically feature the Casio name, and on G-Shock models, the G-Shock logo may also be present. Metal bracelet clasps on Casio watches range from simple folding clasps on budget models to more robust designs on premium lines like the G-Shock GMW-B5000 full-metal series. The clasp design and quality generally correspond to the model's price tier.

Many Casio watches, particularly G-Shock and sport-oriented models, use resin straps rather than metal bracelets, in which case there is no clasp in the traditional sense. The resin strap itself may carry Casio or G-Shock branding. Replacement straps and bracelets are widely available for popular Casio models, so strap markings alone are generally not reliable indicators of authenticity.

What to Look For

Casio 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.

Frequently asked questions

Where are the codes on a Casio bracelet?

Bracelet codes are commonly found on the clasp (fold-over or push-button), on the inside of end links where the bracelet connects to the case, or stamped on the underside of individual links. You may need to remove the bracelet to see all markings.

What do the letters and numbers on the clasp mean?

Clasp codes typically indicate the bracelet model number, the material type, and sometimes a date code showing when the bracelet was manufactured. These help identify replacement parts and verify that the bracelet is original to the watch.
