## Abstract

A portable electronic timepiece includes a display unit which displays an image, and a processor which is operative to display, on the display unit, route information on a traveling route of a user, switch a scale of the route information displayed on the display unit, and in a case where a given point set in association with the route information of a predetermined scale cannot be displayed within a display range of the display unit, change a display mode of the display unit to a display mode that is different from the display mode of displaying the route information.

## Claims

### Claim 1

A portable electronic timepiece comprising:
a display unit which displays an image; and
a processor that is configured to:
display, on the display unit, route information on a traveling route of a user,
switch a scale of the route information displayed on the display unit, and
in a case where a given point set in association with the route information of a predetermined scale cannot be displayed within a display range of the display unit, terminate the display of the route information on the display unit, and display on the display unit a screen including information on a direction and a distance from a current location of the user to a predetermined destination, without displaying the route information.

### Claim 2 (depends on 1)

The portable electronic timepiece according to claim 1, wherein the processor displays on the display unit a screen including the information on the direction from the current location of the user to the predetermined destination and a screen including information on a direction the user is currently facing, alternately on the display unit in response to a manipulation by the user.

### Claim 3 (depends on 1)

The portable electronic timepiece according to claim 1, wherein in a case where a distance from a current location of the user to a predetermined destination is not shorter than a predetermined distance, the processor makes a determination to switch the scale.

### Claim 4 (depends on 1)

The portable electronic timepiece according to claim 1, wherein in a case where the given point falls outside the display range of the display unit and the given point is a point yet to be passed through by the user, the processor changes the display mode of the display unit to a display mode that is different from the display mode of displaying the route information.

### Claim 5

A display method performed by a portable electronic timepiece, the electronic timepiece including a display unit which displays an image, the method comprising:
displaying, on the display unit, route information on a traveling route of a user;
switching a scale of the route information displayed on the display unit; and
in a case where a given point set in association with the route information of a predetermined scale cannot be displayed within a display range of the display unit, terminating the display of the route information, and displaying on the display unit a screen including information on a direction and a distance from a current location of the user to a predetermined destination, without displaying the route information.

### Claim 6

A non-transitory computer-readable storage medium having stored thereon a program that is executable by a computer in a portable electronic timepiece, the electronic timepiece including a display unit which displays an image, the program being executable by the computer to control the computer to perform functions comprising:
displaying, on the display unit, route information on a traveling route of a user;
switching a scale of the route information displayed on the display unit; and
in a case where a given point set in association with the route information of a predetermined scale cannot be displayed within a display range of the display unit, terminating the display of the route information, and displaying on the display unit a screen including information on a direction and a distance from a current location of the user to a predetermined destination, without displaying the route information.
