A band latch mechanism that is configured to connect a wristband to a fitness tracker is provided. The band latch mechanism may be configured to be inserted into a cavity of a housing of the fitness tracker and configured so that any metallic body of the band latch mechanism does not contact metallic surfaces of the cavity in order to prevent an electrical ground from being positioned within a keep-out zone of an antenna of the fitness tracker.

A closure device for releasably connecting two parts with each other includes a first closure member having a rigid first locking protrusion and a second closure member which is attachable to the first closure member and in a closed position is held on the first closure member. The second closure member has a rigid second locking protrusion. The second locking protrusion can be brought into engagement with the first locking protrusion in an engagement direction and in the closed position engages the first locking protrusion in a positive locking manner. The first closure member includes a first magnetic member and the second closure member includes a second magnetic member, the first magnetic member and the second magnetic member being constituted to magnetically attract each other when the second closure member is attached to the first closure member for closing the closure device.

A wristband with straps having a fixed-position keeper and a tang buckle with an elongate-hole tang is provided. The elongate hole may permit the tang to slide for a limited distance along the length of the buckle strap, thereby accommodating different wrist sizes and shapes while reducing the possibility of bridging or tang lift in the band.
