Seiko B26S51SA02W Folding Clasp - 18 mm

The original Seiko B26S51SA02W folding clasp combines a clean design with practicality, which you’ll especially appreciate during everyday wear. The side buttons allow for easy and controlled opening of the clasp with a single motion. This reduces the risk of the watch accidentally slipping off your wrist when putting it on or taking it off. You can adjust the strap length by inserting the pin into the selected strap hole. This solution is gentler on the skin, as it avoids the constant bending and strain typical of a traditional pin buckle.

The clasp is designed for straps that are 18 mm wide at the point where they attach to the clasp.

Select the buckle based on the strap’s width at the buckle attachment point, and make sure you choose the correct variant before ordering.
