DW-5600C
From Wikipedia, the free encyclopedia
The DW-5600C is one of Casio's early G-Shock model watches. Like its immediate predecessors, but unlike most newer models, it was cased in a heavy stainless steel screwback "tuna can." (Most current G-Shocks use a resin or composite case, and a stamped metal back held on by tiny screws.) Internal buffers around the module, a thick mineral-glass crystal, and a replaceable protective plastic bezel made the design resilient enough to withstand abuse which would destroy more traditional watch designs.
It was manufactured from 1987 through 1996. Many are still in use today, in part due to its rugged design. This model has also become something of a collectors' item among G-Shock aficionados.
It was flight-qualified by NASA for space missions'. [1]
The DW-5600C was superseded by:
- DW-5600E composite case and Illuminator, and electroluminescent backlight.
- G-5600 Tough Solar.
- GW-5600 Tough Solar and Wave Ceptor.
- GW-M5600 Tough Solar and Multi-band 5 Wave Ceptor.
[edit] 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.
- Alarm: 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.)
- Dual time: Hours and minutes can be set separately for a second time zone (seconds are synchronized with the home time.) The current home time is also displayed in dual time mode.
- 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, with one split; rolls over at 24 hours.
- Illumination: Backlight is via a tiny incandescent bulb at the left edge of the display.
- Reminder mark: A peculiar feature seldom seen on newer watches, this is a user-enabled display flag which slowly blinks in all modes. It has no function except to serve as a visual reminder to the wearer.
- Shock-resistant design, intended to survive a 10-meter fall.
- Water resistant to 200 meters.
- Battery: One lithium button cell, CR2320 in older models (module 691) or CR2016 in newer models (module 901.) Either was expected to last ten years or more.
