Product Features This watch includes a rechargeable cell. This cell is fed electricity by a solar cell in which light energy is converted to electrical energy. Eco-Drive The watch operates by converting sunlight into electrical energy, which is stored in a rechargeable battery. The rechargeable battery is a clean energy source that does not contain mercury or other harmful substances. When the watch is fully charged, it will operate continuously for approximately 7 months.

Recharging your watch This watch uses a built-in rechargeable cell to store electrical energy. Charge the watch by exposing the dial to light such as direct sunlight or fluorescent lamps. ■ T o ensure optimal operation, be sure to perform the following. • Charge the watch in direct sunlight (outdoors) once a month for 5 to 6 hours. • When you take your watch off, be sure to place it in a location where the dial can receive light.
Wearing clothes that cover the watch may inhibit sufficient light from reaching the watch face, resulting in insufficient charging. Avoid charging the watch under high temperature conditions (approximately 60°C/140°F or more).
Recharging your watch ■ I f the reserve power becomes insufficient (Insufficient Charge Warning Function) When the rechargeable cell charge reaches a low power state, the Insufficient Charge Warning Function engages. This cause the second hand to move in two-second intervals (two-second interval movement). Be sure to immediately fully charge your timepiece by exposing it to light.
■ C harging time by environment Below are the approximate times required for charging when exposing the watch dial to light continuously. Please use this table as a reference only. Charging time (approx.) Environment Illuminance (lx) To work for one day To start working normally when the cell is discharged To become fully charged when the cell is discharged Outdoors (sunny) 100,000 2 minutes 25 minutes 8.5 hours Outdoors (cloudy) 10,000 11 minutes 3.
Setting the Time 1 Pull the crown out to position 2. Pull out the crown just as the second hand is at the reference position (page 18) in order to accurately align to the second. 2 Rotate the crown to set the time. Move the minute hand ahead of the correct time by 5 "minutes" and then return the hand to the correct "minutes". This will minimize the effect of gear play and will provide more accurate hand movement.

• This watch utilizes a special rechargeable cell that does not require regular replacement. However power consumption may increase after using the watch for a number of years due to wear of internal components and deterioration of oils. This may cause stored power to be depleted at a faster rate. For optimal performance, we recommend having your watch inspected (chargeable to the owner) by an authorized service center to ensure operation is within factory specifications.
