An electronic watch may be provided having functionality for space exploration and/or surface exploration on a terrestrial planet. The watch may comprise a time displaying means and a processor subsystem. The processor subsystem may be configured to maintain a coordinated planetary time of a terrestrial planet, obtain longitudinal data representing a longitude of interest on the terrestrial planet which is different from the planet's prime meridian, determine a local true solar time, LTST, at the longitude of interest as a function of the coordinated planetary time and using an equation of time which accounts for orbital eccentricity and rotational axis tilt of the terrestrial planet, and to control the time displaying means of the electronic watch to display the LTST.

This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for displaying directional visual indicators external to a wearable device for navigation. In some aspects, a wearable device may receive navigation signals while the wearable device is in a navigation mode. The navigation signals may indicate a direction of travel. The wearable device may display a first directional visual indicator corresponding to the direction of travel. The first directional visual indicator may be displayed external to the wearable device indicating the direction of travel is a first direction. The first directional visual indicator may be a directional light or a directional projection displayed external to the wearable device in the direction of travel. If the direction of travel changes from the first direction to a second direction, the wearable device may display a second directional visual indicator indicating the direction of travel is the second direction.

An electronic watch may include a housing defining a side wall having a through-hole and a crown assembly including an actuation member. The actuation member may include a crown shaft extending through the through-hole and having an exterior portion defining an input surface and a crown ring coupled to the exterior portion of the crown shaft and electrically isolated from the crown shaft. The crown assembly may further include an optical encoder component attached to the actuation member and defining a group of optical features. The electronic watch may further include an optical detector configured to detect rotation of the crown assembly by detecting motion of the group of optical features and an electrocardiograph sensor comprising a sensing component. The sensing component may be conductively coupled to the actuation member via a conductive path at least partially defined by the crown shaft.

An electronic display device includes measurement sensors that measure respective items, a digital display that displays the items, and a processor. The processor determines a main image related to a measurement of at least one of the items and updates a screen at first timing. Upon displaying the main image related to a measurement of an item other than the first item on the digital display, the processor determines that a sub image is related to measurement of the first item, synchronizes the first timing with update timing that is related to the main image, and simultaneously updates the main image and the sub image.

A display driving circuit for driving a display panel, including a first memory configured to store main image data received from outside of the display driving circuit; a second memory configured to store first additional image data in a normal mode, and to store second additional image data in an Always On Display (AOD) mode having lower power consumption than the normal mode; a normal mode controller configured to operate in the normal mode according to the first additional image data stored in the second memory; and an AOD mode controller configured to operate in the AOD mode according to the main image data stored in the first memory and the second additional image data stored in the second memory.
