The Apple Watch Link Bracelet is a little trickier to work with. Because the Link Bracelet isn't two separate pieces like most bands (because of the butterfly closure), you'll need to separate the Link Bracelet into two pieces.

Close the butterfly closure on your Link Bracelet.

Press in a quick release button on your Link Bracelet (the buttons that let you remove links to adjust the size of your Link Bracelet).

Pull the links apart so the Link Bracelet separates into two pieces.

Press in one of the band release buttons and slide out the Apple Watch band piece.

Press in the other band release button and slide out the other Apple Watch band piece.

Slide in the pieces of your new Apple Watch band (you don't have to hold down the band release button to complete this step).
