A wristworn device having a releasable coupling mechanism for releasably coupling a first strap section and a second strap section about a user's wrist. The wristworn device includes an elongated member that is positioned within a channel of one of the strap sections and which has an actuation section that extends from the channel. A directional force upon the actuation section of the elongated member causes a slidable locking plate in the releasable coupling mechanism to move in a direction and disengage from a locking member, whereby separation of the sections of the releasable coupling mechanism is facilitated upon the disengagement of the slidable locking plate from the locking member.
