Abstract: Bands for wearable devices include multiple band retainers used to maintain engagement between an assembly (e.g., a pair) of bands. Some band retainers may be permanently affixed with the band at a certain location of the band, while other band retainers can be removable. The removable band retainers can be moved to different locations of the band, thus allowing the band retainer to retain another band at different locations. As a result, the assembly of bands can be used with different users, and in particular, users with different wrist sizes. Moreover, using multiple band retainers can provide an engagement force between the bands to withstand higher-impact events, such as swimming and diving. Additionally, bands and band retainers may include one or more liquid-resistant and corrosion-resistant materials.
