• a lug bucket including a circular ledge, the circular ledge having a central opening extending therethrough;
• and
• a puck configured to be removably coupled to the lug bucket, the puck having an enclosure defining a peripheral ring adapted to be seated on the circular ledge when the puck and the lug bucket are engaged;
• wherein the lug bucket and the puck have corresponding locking features that are configured to rotationally and translationally fix the puck to the lug bucket, the corresponding locking features configured to be engaged when the puck is translated relative to the lug bucket and rotated relative to the lug bucket by a predetermined rotation angle, and
• wherein when the puck and the lug bucket are engaged, a top surface of the puck extends above a top surface of the lug bucket and a bottom surface of the puck is accessible through the central opening of the circular ledge.

A method of removably coupling a puck to a watchband assembly, the puck having watch functionality, the method comprising:

• providing the watchband assembly including a lug bucket coupled to a watchband comprising a flexible member configured to be mounted onto a wrist of a user, the lug bucket including a circular ledge, the circular ledge having a central opening extending therethrough, the puck having an enclosure defining a peripheral ring adapted to be seated on the circular ledge when the puck and the lug bucket are engaged;
• translating the puck relative to the lug bucket;
• rotating the puck relative to the lug bucket by a predetermined rotation angle;
• and
• engaging corresponding locking features of the puck and the lug bucket during the translating and the rotating of the puck, the corresponding locking features rotationally and translationally fixing the puck to the lug bucket,
• wherein when the puck and the lug bucket are engaged, a top surface of the puck extends above a top surface of the lug bucket and a bottom surface of the puck is accessible through the central opening of the circular ledge.
