Casio G-Shock DW-5600 History: From 1987 to Solar
In this article
The DW-5600 is the most common model in the G-Shock 5000 Series, beginning as the DW-5600C in 1987, moving to the DW-5600E in 1996, and gaining a solar-powered variant in the G-5600E in 2009. Its square face became a default platform for special color editions and limited collaborations.
The DW-5600C and Its Early Role
The DW-5600C entered the G-Shock lineup as Casio was extending the shock-resistant idea beyond its earliest models, and the broader origin of that effort can be traced in the original G-Shock story. The watch kept the front’s compact square outline while offering a rear that invited closer inspection.
Owners who handled the model could appreciate how the shape fit under a sleeve and how the buttons responded to a press. The case thickness remained modest, which helped the watch slide under shirt cuffs. The bezel protruded just enough to protect the crystal when the watch lay face down. These details may seem minor, but they shaped how the DW-5600C was worn in daily life. Around the same era, Casio was also building digital watches for wearers with different priorities, and another long-lived line from the company is covered in Casio A168: The Full History. The 5600C was aimed at the buyer who wanted durability in a compact rectangular package. Its button placement, bezel shape, and module layout quickly became the template that later versions would follow, giving the 5000 Series a clear visual anchor.
The DW-5600E Redesign and Its MSRP
Casio later released the DW-5600E as a revision of the square design. The changes were significant enough that longtime owners noticed the difference when they held the two models side by side. The new build made the watch lighter on the wrist while keeping the same protective silhouette. The lighter build also meant the watch could be worn for longer periods without fatigue. For many buyers, the lower price point was the deciding factor that brought them into the G-Shock ecosystem for the first time.
The DW-5600E-1V carried an MSRP of US$69.95. That price kept the watch within reach of buyers who wanted a shock-resistant digital timepiece without moving into more expensive G-Shock territory. Casio’s simplified internal construction also made it practical to offer the model in different colors and finishes.
Features on the Square Dial
The DW-5600 includes a stopwatch, countdown timer, alarm, EL backlight with afterglow, flash alert, full auto calendar, 12/24 hour format, and hourly time signal. The EL backlight with afterglow belongs to a longer history of watch illumination; readers who want to see how that technology evolved from radium to modern pigments can explore the story of watch lume. The flash alert adds a visual notification beside the audible alarm, while the full auto calendar handles date changes without manual intervention.
The stopwatch allows split timing for short intervals, while the countdown timer can be set for reminders or intervals. The alarm can be set for a specific time of day, and the flash alert ensures the notification is visible even in noisy environments. The 12/24 hour format lets wearers choose between civilian and military time displays. Together, the feature set supports the watch’s reputation as a no-frills digital tool that can be worn daily without concern.
Special Editions and Material Experiments
Beyond the standard resin version, Casio has used the DW-5600 as a canvas for distinct appearances and material tests. The DW-5600BB is described as a blacked-out Square, offered at a price of €99.90. Its monochrome look appeals to wearers who want the shape without any bright accents. The GX-56BB measures 55,5 × 53,6 × 17,5mm, presenting a larger interpretation of the classic case. Those extra millimeters change how the watch sits on the wrist while keeping the familiar button layout. GX-56 models were also the first G-Shock models that used α-gel, a material innovation intended to soften the contact between the watch and the wrist. The gel adds a cushioned feel that distinguishes these models from the standard resin strap. Collectors often seek out the blacked-out version for its understated aesthetic, while the GX-56BB appeals to those who prefer a bigger presence on the wrist.
If you ever open a case back yourself, a case back opener is the usual tool.
