WVM120 Series (Waveceptor): These Solar Atomic watches with Multi-Band 5 functionality have the ability to receive signals from up to 5 towers located worldwide. They are perfect accessories for business wear, with convenient functions such as world time, 5 alarms and silent mode. They’re also 100M water resistant, which means they can be safely used around water.

Receives time calibration signals and corrects the time automatically. Casio watches with Wave Ceptor technology receive radio waves carrying American Standard Time data transmitted from Fort Collins, Colorado. It then corrects the time automatically for one of four U.S. cities you pre-select depending on your time zone and displays the time.
Multi Band 6 is the worlds first radio-controlled system built to receive time calibration signals from six transmission stations: two in Japan and one each in North America, the United Kingdom and Germany, plus the new station in China.

Casio watches with solar technology, receive thermal and electrical energy that recharges the watch batteries through solar panels on the face of the watch.
A solar panel converts even weak illuminuation from fluorescent lighting into electric power. A rechargeable battery with a large power storage capacity supports stable operation of various functions with high electricity consumption. You never have to worry about the battery running down because it’s a solar battery.

This review is from: Casio Men's WVM120J-1 Solar Atomic Resin Strap Watch (Watch) Some time ago I have sworn that I will only use solar-powered watches that synchronize time with atomic clocks. Initially only quite expensive and 'stylish' models were available, but wearing a timepiece worth several hundred bucks while doing work around the house makes you constantly worried that you scratch precious thing.
This watch is under $100 and has all the benefits of its more expensive 'brothers': - Solar powered quite efficiently - with normal daily exposure to light I'm always at the 'max charge' level (of course living in sunny Nevada helps here). - Time synchronization with the 5 radio transmitters all over the world (USA, England, Germany, Japan*2). I frequently travel to visit family in Europe, so USA and England/Germany transmitter sync is important to me. Many watches in the US only sync with USA transmitter or USA and Japan; the latest models just started supporting new China transmitters; this one is the perfect balance for me. - Time...Read more 56 of 57 people found the following review helpful: By Skip M (Las Vegas) - See all my reviews Amazon Verified Purchase(What's this?) This review is from: Casio Men's WVM120J-1 Solar Atomic Resin Strap Watch (Watch) (REVISED REVIEW) Bought this watch from Amazon 3/31/10. It is easy to read and the atomic auto set feature works fine. Originally I had only one minor problem with the alarm volume. My older ears can't hear the alarm unless it is right next to my ear. I asked Casio if there were solar atomic watches with a louder alarm, and they said that the watch alarm volumes were all the same.
One week ago (July 5, 2010) the watch kept resetting the time and date to 12:00, Jan 1. I could not keep the correct time on the watch either by manual setting or by the atomic setting. I called Casio and they said the battery needed to be replaced. The warranty does not cover the battery or the resin band. So if I shipped the watch to Casio, they would replace the battery for $10 plus $7.95 return shipping. Shipping and battery replacement is over 50% of the purchase price after 3 months of service! The battery is a CTL 1616 and checking the internet, it appears that Casio has had...Read more 22 of 22 people found the following review helpful: By Amazon Verified Purchase(What's this?) This review is from: Casio Men's WVM120J-1 Solar Atomic Resin Strap Watch (Watch) I was looking for a watch that I can rely on in both business and outdoor use. With solar power and atomic timekeeping, I can trust that it will always have power and always be exactly on time. What more could you want in a watch? Well, a countdown timer for cooking and exercise needs, a tough glass dial window, a stainless steel bezel and a resin band that won't muck up from hand washing. In terms of style I was looking for a watch that was clean and functionally elegant (with the functions I need). I looked at analog watches, digital watches, mechanical and kinetic. It came down to very expensive kinetic chronographs, the analog/digital mix watches or this. For the price, I'd rather have a watch that does digital well, than the mixed bag of the analog digital watches. Looks good, easy to read. In terms of power I removed it from the box, kept the Auto EL (automatic backlight) feature on and haven't thought twice about keeping my cuffs up or keeping it in...Read more |
