Embodiments are directed to a wearable device including first and second band straps attached to a device body. A buckle mechanism is configured to attach the first band strap to the second band strap and includes a spring bar attached to an end of the first band strap and a buckle loop engaged to the spring bar. A tang is configured to engage a hole formed in the second band strap to secure the first band strap to the second band strap. The tang defines an aperture that receives the spring bar and is configured to pivot about an offset axis that is offset with respect to an axis of the bar. As the tang is rotated, a restoring force biases the tang toward the buckle loop.
