Claim 0:
1. An electronic watch, comprising:
an enclosure;
a dial positioned along a side of the enclosure and configured to receive a rotational input, the dial comprising:
a dial body; and
a shaft extending from the dial body and extending into an interior volume of the enclosure, the shaft defining:
an end surface; and
an outer peripheral surface;

a rotation sensor positioned within the interior volume of the enclosure and configured to detect the rotational input; and
a variable resistance mechanism configured to produce a variable rotational resistance as the dial rotates due to the rotational input, the variable resistance mechanism comprising:
a friction element positioned along the outer peripheral surface of the shaft and configured to contact the outer peripheral surface of the shaft; and
an actuator configured to vary a force of the friction element on the outer peripheral surface of the shaft, thereby varying the rotational resistance.
