Hope this will help!
1) Remove the original watch strap from the watch. Usually we will have to use a Pin Bar Too to remove that. Look it up on our other accessories section on the right.
2) Open the Nato Strap.
3) Insert the Nato strap on the top Lug
4) And then thru the bottom Lug again
5) Then put the bottom portion back in the Nato Strap
6) Straghten it out and it should look like this. Now it is ready to be put on your hand!
Enjoy your comfortable and easy to watch and reuse Nato Strap!
