Product Tips - Using Your New Solar Watch

We’re excited to bring you a sample of great solar watches in our Casio Solar Watch collection. When you take your personal time keeping to solar, we thought it would be a great idea to give you some basic tips for solar watch power management. This list will give you some common tips and practices to help you to maximize the performance of the solar technology and your experience owning a cool solar watch.

Just like the configuration of a solar panel on a home, a portable solar re-charger, or a solar light, solar watches use a small solar panel integrated into the face of the watch to capture energy from the sun and other forms of light. Solar energy produced by the mini-solar pane is stored in a rechargeable battery also integrated into the watch.

Our Casio watches are ready to go, but it does take some basic understanding of these devices to ge the best out of them. In particular, you need to connect with the sun and world around you and in time you'll acquire a new awareness and experience a slight change in personal behavior as you tune into environmental conditions, cycles of sunlight, clothing choices, and the yearly solar cycles and seasons.

No, you don’t need a degree in meteorology to operate a solar watch, but you may need to make some very basic changes in your behavior to fully capture sunlight, maximize the performance of your watch, and always have an energized battery keeping your timepiece going. This is part of the fun of operating a solar watch…being in tune with the sun and environment and managing this micro photovoltaic technology.

Here are the tips:

Tip #1  Recharge often by finding a place with sunlight to store your watch with the dial facing the light source. But at a minimum (at least once a month), you need to give your watch a nice long (5 to 6 hour) exposure to sunlight by orienting your watch with the dial facing the sun.

Tip #2  Be conscious of the seasons and weakening sunlight, which should give you incentive to follow Tip #1.

Tip #3  Along with fall and winter seasons, be conscious of your cold weather clothing choices as it is likely your watch may be hidden more under long sleeves during winter seasons then in the spring and summer.

Tip #4  Like most electronics, you need to be careful exposing your watch to sunlight while keeping it out of extreme heat for long periods of time. This may be a confusing statement after reading Tip#1. To clarify, places like your car dashboard, or a closed vehicle, get very hot without airflow. Extremely high temperatures can damage watch parts or cause your solar watch to malfunction...just like other watches and electronics. It can also cause damage or fading to urethane style bands.

Tip #5  Like all solar powered products, sufficient amounts of light and time of exposure are very important to charging. You need to have sufficient sunlight for charging and your watch is likely not broken if it is not starting. Instead, it just needs that great sunny day exposure and a good solar charge to juice up the battery. You can avoid a full drain on the battery by following the Tips above.

Tip #6  It takes longer to recharge in room light versus sunlight. Here are some guidelines on light source exposure (lux = unit of illuminance for measuring light intensity) options for your solar watch. Keep this in mind when you adjust for solar charging.

a. Under direct sunlight - about 100,000 lx
b. A cloudy day - about 10,000 lx
c. Room light – 2” from 30W-fluorescent lamp - about 10,000 lx
d. Room light – 8” from 30W-fluorescent lamp - about 3,000 lx
e. Room Light – Normal office light - about 700 lx

Tip #7  This may seem like common sense, but a solar watch cannot recharge in dark conditions. Under the following conditions, your solar watch will likely run out of energy.

a. When a solar watch is stored in a pocket or dark location.
b. When a solar watch is concealed under a sleeve.
c. When a solar watch is stored under something blocking any light exposure for a long time.

Tip #8  If you work and play outside, your watch will likely get adequate exposure to maintain the battery charge while you your wrist, but it is still advisable to make sure to place it by a window and expose it to direct sunlight when not wearing it.

Tip #9  A solar watch is an electronic and mechanical device, and like other devices of this nature, it is advisable to have your solar watch serviced every 3 or 4 years in order to ensure it functions perfectly and will be able to be used for a long time.
