1. An expandable band system to assist in securing a wearable device to a user, the system comprising:
a pair of sheath assemblies; and
an inner band assembly movably coupled to and spanning between the sheath assemblies, the inner band assembly including a pair of biasing mechanisms coupled to the sheath assemblies for biasing the sheath assemblies together towards a retracted configuration, and
wherein the expandable band system is movable between the retracted configuration, in which the sheath assemblies are relatively closer together, and an expanded configuration, in which the sheath assemblies are relatively further apart,
wherein each biasing mechanism includes an elongated compression spring, and
wherein the inner band assembly further includes a band-like enclosure that surrounds the elongated compression springs of the biasing mechanisms.
