Watchband connection mechanism system and method

Abstract

A watchband connection mechanism includes a watchband with a watchband housing and a cam rotatable between a first position where the cam extends from the watchband into a watch ledge in a watch side cavity and a second position where the cam is recessed in the watchband housing. A watch includes a watch housing, a watch cavity in the watch housing for receiving at least a portion of the watchband, and a button coupled to the watch housing and movable with respect to the watch cavity. In operation, the watchband is received in the watch cavity of the watch housing, which enables the cam to rotate into the first position to extend from the band into the watch ledge. The watch housing prevents the watchband from uncoupling with the watch in the first position of the cam due to the cam securing in the watch ledge. The user then depresses the button to move the cam into the second position, which is back within the watchband, to uncouple the watchband from the watch.
