How to fit the Casio G-Shock Nato Strap Adapters

  1. Remove the standard polyurethane strap and use back the removed spring bars to attach the adapter.
  2. As you will not be able to see the spring bar hole on one side, it is little tricky to get the spring bar in place. Keep trying by pushing the end of the spring bar with Spring Bar Tools "Y" end.
  3. Once you get the spring bar into the lugs, use the springbar tool to push it in until you hear a click.
  4. To make sure the springbar fitted the lugs hole, try pulling the adapter to make sure its secure before slotting the NATO strap.
