Rotatable control button assembly for a wearable device

A wearable electronic device comprising:

• a housing;
• a controller enclosed within an interior of the housing, wherein the controller comprises a processor and memory;
• a Hall effect sensor enclosed within the interior of the housing and positioned adjacent to or engaged with an interior surface of the housing, wherein the Hall effect sensor is communicatively coupled with the controller and configured to generate control signals for use by the controller to control functionality of the device;
• and
• a control button assembly engaged with the housing, wherein an exterior of the housing presents a cavity in which at least a portion of the control button assembly is received,
• wherein a proximal end of the control button assembly comprises a magnet,
• wherein a distal end of the control button assembly comprises a crown that is rotatable with respect to the housing, and wherein the control button assembly is configured such that rotation of the crown causes a corresponding rotation of the magnet, wherein upon the magnet being rotated via rotation of the crown, the Hall effect sensor is configured to detect the rotation of the magnet,
• wherein the housing comprises a sidewall, and wherein the sidewall entirely separates the control button assembly from the Hall effect sensor, the sidewall forming a continuous material barrier between the control button assembly and the Hall effect sensor, and wherein the control button assembly does not extend through the housing into the interior of the housing.
