Attachment mechanism architectures for a watch band

A watch band comprising:

• a watch band connector comprising:
• electrical connectors fixed to a movable sled, wherein the electrical connectors and the movable sled are movable together between an engaged position and a disengaged position;
• and
• a shuttle connected to the movable sled by a cam;
• and
• a strap portion coupled to the shuttle, wherein movement of the strap portion away from the watch band connector rotates the cam, and rotation of the cam pushes the movable sled away from the shuttle to move the electrical connectors from the disengaged position to the engaged position.

A watch comprising:

• a watch body;
• a watch band connector connectable to the watch body, the watch band connector comprising:
• a catch member configured to engage with the watch body to physically couple the watch band connector to the watch body;
• electrical connectors movable between a disengaged position and an engaged position;
• and
• an interaction interface being exposed and rotatable to move the electrical connectors from the disengaged position to the engaged position.
