Apple's Watch release is still at least a month away, but thanks to 'mix your watch,' you can start building one now. The interactive web tool allows you to create your perfect Apple Watch by customizing the case color, band color and band material.
It uses stock images from Apple's website, and an image-based UI that allows you to customize each element. So if you want to see what a dark aluminum case would look like with a black leather band, simply select them, and watch the colors change.
