1. Unhook the band at the buckle clasp and lay the watchband flat
(face down).
2. The removable links are the slotted links on either side of the
clasp. In the center of each slot is a tiny connector pin. Insert a
sharp pointed object(like a pin or the tip of a nail file) in the slot
and push the pin away from the clasp.
3. Gently slide the link slightly to one side. Remove the pointed
tool, and slide the link off completely. Repeat steps 2 and 3 for
the desired number of links.
