On the rear of your Apple Watch, there are two small buttons - one at the top and one at the bottom of the back plate. These buttons are used to release the existing band (if installed).

To remove the existing band, press and hold one of the release buttons. This will allow yout to slide the band out of the slot. Repeat this step for both the top and bottom to remove the band completely.

 
To install the new band, simply slide the adapters into the slot (one side of the Apple Watch band adapter will have a silver magnet in the middle, this side of the adapter should face the same direction as the backplate). You will know the band has been intalled securely once you hear a slight click.
