1. Place the spring bar into the bottom spring bar compartment before placing the watch on top.

2. Insert one end of the spring bar into the hole on the watch lug.

3. Use your changing tool to compress the other end of the spring bar, so it slides inside the watch lug. Make sure both ends of the spring bar securely snap into their holes, or the strap will fall off the watch.

4. Repeat the process on the other side of the watch.
