As a company with cutting-edge electronic technology developed for pocket calculators, Casio entered this field confident that it could develop timepieces that would lead the market.Today, Casio is focusing its efforts on solar-powered radio-controlled watches: the built-in solar battery eliminates the nuisance of replacing batteries, atomic timekeeping means the users never have to reset the time. Recently, Casio launched a series of Bluetooth watches that sync to the users cell phone to automatically update the time. Casio is always moving time forward. See more

Review: Best beater watch - The Casio F105W is a great beater watch because it's inexpensive, compact, lightweight, and good-looking. My favorite of the small Casio offerings. The display is small (I prefer the large display of a Timex Ironman 30), but it's an ok compromise. Also, beware that the strap is short but that's a pro for wrist sizes of 7" or less. Includes basic alarm, hourly chime, and stopwatch functions with ELD illumination. Can't beat it for the price.
Review: Best simple digital watch ever! Takes a licking & keeps on kicking! - Love this watch. Have been wearing this model since the 1980s. Sturdy, functional, reliable, accurate & lasts for years & years. Easy to use and set up the date, time, stop watch, timer and alarm. All functions work as they should. Choice of on the hour reminder chime, 12 or 24 hour display and the alarm beeps gradually accend in volume, gently waking the wearer without disturbing those nearby who want to keep sleeping. The back light dims out after several years. The watches themselves have never cracked or broken. Rough on watches. One was replaced when lens became cloudy, covered in an accumulation over time of tiny scratches from repeated contact with rough surface . Another replacedment was bc one of the holes where the bar for the watch strap sits became enlarged & would not hold bar any longer after the strap got hung up & thankfully pop the bar out, saving my wrist. The strap has hung up before, breaking the strap instead of popping out the bar. I'm not 100%sure but I think it was a newer replacement watch band that pulled the bar out Battery & strap sre simple to replace. Oh and this watch can handle being caked with mud, paint, dust, sand, etc..., covered in shampoos, lotions, etc.., and even sprayed with cleaning liquids (bleach, white vinegar, rubbing alcohol, hydrogen peroxide, and more Never take it off, except to clean it or . It's waterproof in the pool, tub, shower, lake & ocean snorkeling & even held up on a 30 min. shallow scuba dive average depth 20ft. Ladies, if you like simple, practical, watches, but find ladies' digital watches too small and men's either too big and thick check this watch out. I don't even notice I'm wearing it. It doesn't catch on clothing or anything except for when overcome by an occasionsl knucklehead moment and move too fast before looking. Correction. When it's really cold and multiple long sleeve layers are wrapped in sleeves with elastic wrist cuffs, adjust xthe watch location for comfort.and move move way too fast farms, in the barns, corals, pastures and pens Best simple digital watch, ever.
