The quick-disconnect style of a metal watchband's clasp allows the band to be adjusted for the best fit. A metal watchband provides comfort on your wrist without the pressure that a spring loaded expansion band may exert. A series of adjustment holes and a telescoping spring bar on the metal watchband clasp provide the means by which to tighten the band. You can tighten your own watchband in 10 minutes or less with an improvised tool made from a paper clip.
Open the metal watchband clasp to become familiar with its adjustment features. The solid metal swivel plate is connected at the end of the clasp and should not be removed. The watchband itself is fastened to the other end of the clasp in one of the adjustment holes, and it is this end that will be worked on.
Unfold one end of the paper clip to extend the tip of the metal. Depress the spring bar which holds the metal watchband to the clasp by inserting the paper clip into the corresponding hole. The amount of depression required to release the band is slight.
Pull the watchband from the clasp with a hand over the clasp to prevent the spring bar from popping out inadvertently and perhaps being lost. The spring bar will release itself from the hole on the other side of the clasp as this is done.
Place the end of the metal watchband with the spring bar into position at the hole chosen for the new fit. One end of the spring bar must be placed into the desired hole and the other end must be placed at the leading edge of the clasp directly across from that hole.
Depress the top of the spring bar at the leading edge until it is able to be pushed into the clasp. Snap it into the appropriate hole opposite the hole that the other end of the spring bar was placed into. This can be accomplished with either the improvised paper clip or a thumbnail of the hand. Keep the clasp covered with one hand to prevent the depressed spring bar from popping out.
Close the clasp and check for desired tightness and comfort of the watchband.
If the first adjustment does not bring a satisfactory fit, then further adjustments can be made.
