• The illumination provided by the backlight may be hard to see when viewed under

direct sunlight.

• The portion of the display illuminated by the backlight depends on the watch model.

With some models, smaller indicators may not be made visible by backlight illumi-

nation.

Home City time setting in the Timekeeping Mode.

• GMT differential is calculated by this watch based on Universal Time Coordinated

(UTC) data.

• The seconds count of the World Time is synchronized with the seconds count of the

Timekeeping Mode.

and Daylight Saving Time (DST). It also includes information about when the switch

is made.
