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 signal reception is excellent in Nevada, bot inside the buildings and outside. From my previous experiences it should mean good reception throughout the West Coast and (maybe!) some problems inside solid-construction buildings in New England and Florida.
- Unlike some cheap models of watches and clocks, this one reads Daylight Savings Time data straight from the radio signal, so it 'springs ahead' and 'falls back' at the correct dates. Some older clocks have hard-coded DST transition dates and are confused after the recent DST changes in the USA.
- I love 'Auto EL' feature: the watch turns on Electro-Luminescent backlight for two seconds when it is dark and the wearer positions hand appropriately. Perfect for the movies, night flights and similar situations.
- I usually prefer metal bands, but resin band in this model is surprisingly good quality and wears OK.
- Button operation seems to be reliable so far.
- The glass is scratch resistant and placed recessed in the metal panel - so far I managed to keep it clear, which is unusual for me.

Amazon had the best price for this item, better than Fry's and Casio website. The watch arrived on time and in good shape.
