About this product
Bought a strap one size long, or your wrist sits between holes — an adjustable folding clasp with an extender section fixes both without punching new holes or replacing the strap. 316L is the standard steel for clasps and shrugs off daily sweat and handwashing. The most common sizing mistake: measuring the case diameter instead of the strap width at the lugs — a 38mm watch may well wear a 20mm strap. Measure your old clasp or the strap end before ordering, then match the finish to the case: polished with polished, brushed with brushed.
