Galaxy Gear Neo on NATO strap
Quick video on how to swap the straps. The Neo has speed pins so its easy to take off. However, since the spring bars are inside the strap, you need to buy 22mm spring bars.
I actually put the watch upside down on the video, but the process remains the same.
You'll also need to tool if you want to remove the strap later since they won't be speed pin (unless its NATO or ZULU straps)
