Charging Time Guidelines

Charging the watch daily for the approximate times shown below should maintain a charge of 3515_icon_inl_LOW or higher.

When the charge level is 3515_icon_inl_LOW , you will still be able to use the current time screen, and stopwatch, timer, world time, and alarm functions.

Checking the Charge Level

Note

Actual charging time depends on the charging environment, watch settings, and other factors.

Charging with the Charging Cable

Charge Recovery Times

Blank display HIGH (Full charge)	Approx. 3.2 hours *
CHG LOW	Approx. 10 minutes
LOW Level 1	Approx. 15 minutes
Level 1 HIGH (Full charge)	Approx. 3.1 hours

Approx. 6 hours when ambient temperature is 5°C to 10°C (41°F to 50°F)

Solar Charging

Time required to maintain the current time display by solar charging even when the battery level is “LOW”

Light Level (Lux)	Approximate Charging Time
50,000 lux (Sunny day outdoors, etc.)	9 minutes
10,000 lux (Sunny day near a window, etc.)	42 minutes
5,000 lux (Overcast day near a window, etc.)	83 minutes
500 lux (Indoor fluorescent lighting, etc.)	14 hours

Note

Charging is performed even with exposure to indoor fluorescent lighting (500 lux). The watch will be able to maintain a charge of 3515_icon_inl_LOW or higher if it is exposed to indoor fluorescent lighting for eight hours a day, in addition to light near a window on a sunny day (10,000 lux) for two hours a week.
