`ABSTRACT
`( 57 )
`An electronic wristwatch operable in two power modes . The
`wristwatch has an inertial sensor for detecting a gesture on
`a cover glass of the wristwatch . A touch panel is provided
`underneath the cover glass for detecting the gesture . Gesture
`detection by the inertial sensor is combined with gesture
`detection by the touch panel for triggering a switch from a
`first power mode to a second power mode .
