DW-5600E

The Casio DW-5600E is a model of digital watch, manufactured by the Japanese firm Casio and a member of Casio's G-Shock product line. Casio introduced this model in 1996. It has 200M water resistance, one alarm, a countdown timer and a stopwatch. These features trigger an audible alarm.

This model replaces the older Casio DW-5600C and features Illuminator, an EL backlight with flash function. The dual-time function was deleted, but the current time is also displayed in countdown timer and stopwatch mode.

One of the major differences between this model and the original DW-5600C is the use of a polymer case material with a stainless steel case back secured with four screws. The original design featured a stainless steel case and screw-down case back and is highly sought after by collectors.

It has been flight-qualified by NASA for space missions. [ [http://nasaexplores.com/show2_articlea.php?id=02-024 NASAexplores - Express Lessons and Online Resources ] ]

Three subsequent iterations of this designed have been released:

* G-5600 Tough Solar.
* GW-5600 Tough Solar and Wave Ceptor.
*GW-M5600 Tough Solar and Multi-band 5 Wave Ceptor.

Features

* Time display in 12-hour or 24-hour format. In regular timekeeping mode, the current home time is displayed to the second, along with the month, date, and day of the week, without any button presses.
* Auto-calendar correctly calculates month lengths, leap years and days-of-the-week between 1985 and 2029.
* One alarm. An unusual feature is that in addition to the hour and minute, a month and/or date may optionally be set, so the alarm will only sound during the specified month or on the specified day of the month.
* Time signal (hourly chime.)
* Countdown timer: Can be set for any duration from one second up to 24 hours, in one-second increments; optional auto-repeat function. The current home time is also displayed in countdown timer mode.
* Stopwatch: 1/100th second, which measures net time, split time, and first- and second-place times; rolls over at 24 hours.
* Illumination: Backlight is via Illuminator, an electroluminescent backlight, where a blue/green luminescence makes the whole display visible at any light conditions.
* Shock-resistant design, intended to survive a 10-meter fall. The new composite-case and steel panel back made the watch about 30% lighter, and better fitted to the wrist.
* Water resistant 200M.
* Battery: One lithium button cell, CR2016 (module 1545). Was expected to last two years or more.
