Insert the small needle tool supplied with your watch, into the hole on the side of the strap and push the pin out in the direction of the arrow (see arrows on the back of the strap). Using a small household hammer, tap lightly until the pin comes out the other side. Grasp the pin and pull out. Remove the end clasp link first and then remove the desired amount of middle links.
Remove or add required strap links. If removing more than one strap link, remove an equal number of links from both sides to keep the strap even and symmetrical.
After removing or adding the necessary number of strap links, re-connect the clasp link by placing the pin back in the opposite direction of the arrows (pink goes in narrow end first). Tap the pin back through using the hammer to finish until flush with the strap.
