Product Description

The PRG550 series is a 3 hand analog watch model with an LCD window. The triple sensors measure compass bearing in compass mode the second hand becomes the compass needle pointer; altitude/atmospheric pressure and temperature. The multipurpose second hand points towards magnetic north and can indicate the latest change in atmospheric pressure or show a change in altitude from a pre-selected location; depending on the function selected. While the LCD displays numerical sensor information such as compass direction angle value; altitude; atmospheric pressure; and temperature; the PRG550-1A1’s full auto LED light activates with just a flick of the wrist and operates by Casio’s Tough Solar Power technology; allowing readings to be accomplished with ease. Casio’s Tough Solar Power technology adds to the PRG550 series efficiency by allowing the time piece to power down when not exposed to light for a certain period of time; thus conserving energy. Black resin band analog and digital watch with blackface.


With the launch of its first watch in November 1974, Casio entered the wristwatch market at a time when the watch industry had just discovered digital technology. 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.
