There are few third-party band options available for the Apple Watch at the current point in time given that it just launched a week and a half ago, but those of you who purchased a stainless steel Apple Watch with a Classic Buckle or Modern Buckle band can use the components from those bands to connect standard watch bands to your Apple Watch devices.
In a newly published video, Lewis Hilsenteger of Unbox Therapy walks through the process of using the parts in the Classic Buckle band to connect a 22mm third-party watch band to the Apple Watch.
Along with a compatible Apple Watch band, a tiny pentalobe screwdriver is also required to swap out the band, but those are available at little cost. With a Classic Buckle and the screwdriver, making a swap is as uncomplicated as simply removing two screws, pulling apart the connector, sticking the pieces into another watch band, and putting it back together again.
