Charging the Watch

The face of the watch is a solar panel that generates power from light. The generated power charges a built-in rechargeable battery, which powers watch operations. The watch charges whenever it is exposed to light.

Charging Guide

Whenever you are not wearing the watch, be sure to leave it in a location where it is exposed to light.

ξ Best charging performance is achieved by exposing the watch to light that is as strong as possible.

Warning!

When wearing the watch, makes sure that its face is not blocked from light by the sleeve of your clothing.

ξThe watch may enter a sleep state (page E-10) if its face is blocked by your sleeve even only partially.

Leaving the watch in bright light for charging can cause it to become quite hot. Take care when handling the watch to avoid burn injury. The watch can become particularly hot when exposed to the following conditions for long periods.

ξOn the dashboard of a car parked in direct sunlight

ξToo close to an incandescent lamp

ξUnder direct sunlight
