Day

It can take anywhere from about 10 to 40 seconds for the day indicator to change after timekeeping reaches midnight. The mode hand moves as the day indicator changes. The day may not be indicated correctly while the watch’s crown is pulled out.

Solar Charging

This watch runs on power supplied from a rechargeable (secondary) battery that is charged by a solar panel. The solar panel is integrated into the face of the watch, and power is generated whenever the face is exposed to light.

Charging the Watch

When you are not wearing the watch, put it i a location where it is exposed to bright light

While you are wearing the watch, make sure that its face (solar panel) is not blocked from light by the sleeve of your clothing. Power generation efficiency is reduced even when the face of the watch is blocked only partially.

Important
Depending on light intensity and local conditions, the watch may become hot to the touch when exposed to light fo  charging. Take care to avoid burring injury after charging. Also, avoid charging the watch under high temperature conditions like the ones described below

• On the dashboard of a vehicle parked in the sun.
• Near an incandescent light bulb or other source of heat.
• Under direct sunlight or in other hot areas for long periods.

Remaining Charge and Dead Battery

You can determine if the charge level is low by checking the hand movement. Functions become disabled as battery power goes low.

Important
Should the battery go low or go dead, expose the face (solar panel) to light as soon as possiblel

Note
Exposing the watch face to light after the battery goes dead will cause the second hand to revolve counterclockwise until it stops at second 57. This indicates charging has started.
