It varies by line. Classic vintage-style Casio watches commonly use an 18mm band, while Edifice and Pro Trek models often run 20mm to 22mm. We stock replacement bands from 12mm to 28mm, and our lug width guide shows how to measure the gap between your lugs to be sure.
No. Quick-release bands have a small lever on the spring bar that lets you swap the strap by hand. Traditional spring-bar styles, including most of our steel Jubilee and President-style bracelets, need a small spring-bar tool. Our step-by-step video guide covers both methods.
Jubilee, President-style, and standard link bracelets are shortened by pushing out the connecting pins to remove links, then reinserting the pins, no cutting required. Full instructions are in our bracelet sizing guide.
Silicone and rubber diver-style straps resist water, sweat, and UV exposure, making them the most durable choice for outdoor and sport use. Ballistic nylon is a good alternative if you prefer a fabric look with similar durability. Leather and polished steel are better suited to dressier Edifice styles.
Yes. Compatibility is based on lug width and lug style, not case material, so our bands fit resin, stainless steel, and mixed-material Casio cases as long as the lug width matches.
