These clasps fit most standard watch straps as a replacement for buckle and pin connectors. They have a central pin that fits through the straps pin hole and close over clicking in place.
The size stated is the inside measurement of the buckle and not the strap size. Often watch straps taper. For example many 20mm Watch straps will require a 18mm buckle.
It is advised that you measure the strap end before ordering. If you need any assistance please feel free to message us.
