There is arguably no more recognizable digital watch design in the world than the classic Casio 5000/5600 series.
Despite a vast array of sizes, functions, materials, color schemes, and price ranges, the basic design of the octagonal digital G-Shock remains almost unchanged and instantly recognizable in all its variations. When a model comes along that significantly alters the very foundation of G-Shock, it becomes an important event. The new Casio G-Shock GMWBZ5000RC-1 with its rainbow ion plating showcases updates to the classic G-Shock formula in vibrant colors, equipped with a modern MIP LCD display and a host of other technical enhancements.
Case and Design: Evolution of a Classic with New Materials
At first glance, the case dimensions of the Casio G-Shock GMWBZ5000RC-1 do not differ significantly from previous “Full Metal” versions of this model. With a width of 43.6 mm and a thickness of 13 mm, the stainless steel case is slightly larger than its predecessor, but the wearing experience is quite different. The main reason is the updated design of the case sides. Previously, in both plastic and metal versions, the outer case of the octagon (referred to by Casio as the “bezel”) extended to the back cover, creating a monolithic, almost architectural image with a massive industrial character. In the new model, Casio employs a two-part construction - the traditional outer case covers only part of the side surface (and is completely absent in the area of the protected lugs), where it joins with an additional mid-case section.
This solution forms a visible seam along the sides of the case, further emphasized by cutouts at the “3 o’clock” and “9 o’clock” positions, revealing the inner layer of the case. Although all G-Shock watches guarantee not only high shock resistance but also water resistance up to 200 meters, such cutouts may raise questions, but the brand assures that the GMWBZ5000RC-1 fully meets reliability standards.
Two-Layer Case and Rainbow Ion Plating
The two-component case construction allows for a more sculptural and dynamic profile with large cutouts that reduce the visual weight of both the lugs and the case overall. This also enables the use of multilayered and multi-material solutions characteristic of top-tier G-Shock models in a more accessible segment.
From above, only radially brushed gold inserts in the lug recesses are visible, but the side view reveals the full novelty. The lower part of the case is covered with a bright rainbow ion gradient, transitioning from sunset orange at “12 o’clock” to deep marine blue at “6 o’clock” through a spectrum of red, violet, and indigo shades. This color transition not only visually separates the lower case from the upper, emphasizing traditional grooves and recesses, but also evokes the heat-induced color change of high-performance exhaust systems. Thus, Casio connects the durability and reliability of the G-Shock with the metal case, as if hinting that the watch has already passed the “fire test.” The engraved case back and recessed, polished control buttons will be familiar to brand enthusiasts.
Dial with MIP Display: Modern Readability and Classic in One
An important update is the new digital dial with a MIP
(memory-in-pixel) display. Using the Casio Watches app, you can switch between the classic LCD font and the new, more contrasting and easily readable style (as shown in the photo). The negative style display is brighter and clearer than traditional negative LCDs, convenient in any lighting, and retains the technical charm of the G-Shock.
Many interchangeable sub-displays and functions will be familiar to series fans, but the main advantage of the new dial is the combination of classic and modern elements. For example, the Tough Solar charging system is integrated into the texture of the inner bezel with a “brickwork” pattern, while the surrounding accent ring has a gradient from yellow to blue, echoing the lower part of the case.
The Casio G-Shock GMWBZ5000RC-1 is equipped with its own quartz movement Module 3575. As expected from a G-Shock, it offers a wide range of functions:
- Perpetual calendar
- Chronograph accurate to 1/100th of a second
- World time
- Five programmable daily alarms
- 24-hour countdown timer
- Bluetooth connectivity
- LED dial illumination
Additionally, the watch has a solar battery power reserve of up to 22 months and automatic time correction by radio signal, ensuring almost perfect accuracy. Without a radio signal, the module's accuracy is ±15 seconds per month.
Stainless Steel Bracelet: Classic Without Changes
The only element that has remained virtually unchanged from previous “Full Metal” versions is the stainless steel bracelet. It is made of solid links with linear brushing, polished bevels, and recessed indentations, creating a robust and massive appearance. This bracelet has become a natural extension of the 5000/5600 design, although it actually appeared much later than the base model.
When worn, the bracelet gives the watch a solid weight and a sense of reliability, but thanks to its enveloping form, it is comfortable even on medium-sized wrists (my wrist size is 17.2 cm).
Conclusion: Classic Updated with Technical Progress and Bright Style
The Casio G-Shock 5000/5600 series is one of the most popular and recognizable in the world of digital watches. Despite the enormous number of models, significant changes to the basic design are rare. The new Casio G-Shock GMWBZ5000RC-1 proves that classics can successfully evolve - with a sleeker, more colorful case and an improved dial. These watches are already available at official dealers for a recommended price of $880 USD at the time of publication.
This model combines the traditional reliability of G-Shock with modern materials and technologies, making it an interesting choice for fans of functional and stylish digital watches.
