Patent attributes
Wearable electronic devices, such as watches, can be provided with an attachment system for connecting and releasing a removable module that interfaces with some portion of the electronic device. For example, a watch can include locking mechanisms that allow a user to connect a watchband to a watch housing by moving the watchband directly toward the watch housing. An attachment unit of a watchband can be moved in a direction along its own longitudinal axis to securely engage the watch housing. Once engaged, one or more locking mechanisms limit longitudinal movement of the attachment unit away from the watch housing. One or more locking mechanisms also limit lateral movement of the attachment unit with respect to the watch housing until a user releases the one or more locking mechanisms and enables the lateral movement.
