People of all sizes buy metal watch bands that just don't fit. There are several choices about how to deal with the dilemma. Sometimes the store will size a new watch for free. You can take the watch band to a local jewellery store, but it may charge a small fee for sizing a watch it didn't sell. Another option is to size the watch at home. Leaf springs are a type of pin that holds the links of a metal watch band together.
Put on the watch and estimate the number of links to remove.
Spread a soft cloth on a firm surface. Lay the watch face down on the cloth.
Look carefully at the back side of the links, starting at the clasp. There will be tiny arrows on each of the links that are held with a leaf spring.
Push the tab of the leaf spring in the same direction as the arrow with the end of the tweezers. The tab of the spring will extend outside of the watch band.
Grasp the tab of the leaf spring with the tweezers and pull the spring from the watch band.
Separate the link from the clasp. Remove the leaf spring from the link on the other side of the clasp and set the clasp aside.
Remove links from both sides of the watch band until it fits the wrist.
Line up the link of the clasp with the final link of the watch band.
Insert the leaf spring pin into the notch of the joined links. Press the leaf spring in until it is flush with the side of the watch band. Repeat with the other side.
Try the finished watch band on and check it for size.
To prevent losing any of the tiny springs, place a loop of tape on the table next to the work area. Stick each pin to the tape when removed. Discard or place in a zipper baggie with the links to save for future repairs.
