A wearable electronic device, comprising: a housing; a band attached to the housing and configured to attach the wearable electronic device to a user; a display positioned within the housing and defining a front face of the wearable electronic device; a crown positioned along a side of the housing; a rotation sensor configured to detect a rotational movement of the crown; a contact sensor configured to detect a contact between the user and the crown; and a processor operatively coupled to the contact sensor and the display and configured to: while a contact is detected between the user and the crown: modify a graphical output of the display in accordance with the rotational movement of the crown; and determine a speed of the rotational movement of the crown; and in response to detecting a release of the contact between the user and the crown: if the speed of the rotational movement of the crown, as determined prior to detecting the release of the contact between the user and the crown, is above a predetermined threshold, modify the graphical output of the display without regard to rotational movement or absence of rotational movement of the crown if the speed of the rotational movement of the crown as determined prior to detecting the release of the contact between the user and the crown, is below the predetermined threshold, cease to modify the graphical output of the display. a housing; a band attached to the housing and configured to attach the wearable electronic device to a user; a display positioned within the housing and defining a front face of the wearable electronic device; a crown positioned along a side of the housing; a rotation sensor configured to detect a rotational movement of the crown; a contact sensor configured to detect a contact between the user and the crown; and a processor operatively coupled to the contact sensor and the display and configured to: while a contact is detected between the user and the crown: modify a graphical output of the display in accordance with the rotational movement of the crown; and determine a speed of the rotational movement of the crown; and in response to detecting a release of the contact between the user and the crown: if the speed of the rotational movement of the crown, as determined prior to detecting the release of the contact between the user and the crown, is above a predetermined threshold, modify the graphical output of the display without regard to rotational movement or absence of rotational movement of the crown if the speed of the rotational movement of the crown as determined prior to detecting the release of the contact between the user and the crown, is below the predetermined threshold, cease to modify the graphical output of the display. modify a graphical output of the display in accordance with the rotational movement of the crown; and determine a speed of the rotational movement of the crown; and in response to detecting a release of the contact between the user and the crown: if the speed of the rotational movement of the crown, as determined prior to detecting the release of the contact between the user and the crown, is above a predetermined threshold, modify the graphical output of the display without regard to rotational movement or absence of rotational movement of the crown if the speed of the rotational movement of the crown as determined prior to detecting the release of the contact between the user and the crown, is below the predetermined threshold, cease to modify the graphical output of the display. if the speed of the rotational movement of the crown, as determined prior to detecting the release of the contact between the user and the crown, is above a predetermined threshold, modify the graphical output of the display without regard to rotational movement or absence of rotational movement of the crown if the speed of the rotational movement of the crown as determined prior to detecting the release of the contact between the user and the crown, is below the predetermined threshold, cease to modify the graphical output of the display.
