The lineup includes six references, with resin-bezel models and stainless-steel-bezel GM versions. The key choice is whether you prefer the 5600’s digital display and color-treated glass or the 2100’s analog-digital dial and separately produced rainbow effect.
What models are in the Rainbow Brick Wall G-SHOCK collection?
Casio’s US collection page lists six models. The 5600 references use a square digital design; the 2100 references use an octagonal analog-digital design. Within each design, the GM variants add a stainless-steel bezel.
| Model | Design | Bezel | Rainbow treatment |
|---|---|---|---|
| DW-5600RW-1 | 5600 digital | Resin | Rainbow gradient vapor-deposited on the glass, with black printing |
| GM-5600RW-1 | 5600 digital | Stainless steel | Rainbow gradient vapor-deposited on the glass, with black printing |
| GM-5600BRW-1 | 5600 digital | Stainless steel | Rainbow gradient vapor-deposited on the glass, with black printing |
| GA-2100RW-1A | 2100 analog-digital | Resin | Silver vapor deposition, partial laser removal, and multicolor printing on the dial |
| GM-2100RW-1A | 2100 analog-digital | Stainless steel | Silver vapor deposition, partial laser removal, and multicolor printing on the dial |
| GM-2100BRW-1A | 2100 analog-digital | Stainless steel | Silver vapor deposition, partial laser removal, and multicolor printing on the dial |
References and suffixes vary by market. For example, Casio Japan lists the DW-5600RW-1JF, while the US page uses DW-5600RW-1. Check the reference shown by the seller and the applicable regional Casio page rather than assuming every market uses the same suffix. Casio US collection · Casio Japan DW-5600RW-1JF page
What is the difference between the DW-5600RW and GA-2100RW?
5600: digital display and rainbow glass gradient
The DW-5600RW-1 and GM-5600 variants are digital watches. Casio says the brick pattern is made with rainbow-hued gradient vapor deposition and black printing on the glass. The special deposition process means the gradient is unique on each watch, so the color distribution can differ from the product images and from another example of the same model. Casio Japan makes the same individual-variation note for the DW-5600RW-1JF.
#1 Best Overall
- Shock-Resistant: Iconic G-Shock watch with a tough, shock-resistant case designed to withstand impacts and vibrations.

- Digital Display: Large digital display with backlight and multi-function LCD showing time, day, date, and alarm.
- Stopwatch and Countdown Timer: Equipped with a 1/100th second stopwatch and countdown timer.
- Rainbow vapor deposition reproduces the symbolic brick wall imagery in brilliant rainbow hues that shift and change depending on the light.
2100: analog-digital display and a dial-based effect
The GA-2100RW-1A and GM-2100 variants combine analog hands with a digital display. Casio describes a different dial process: silver vapor deposition is applied, portions are removed by laser, and multicolor printing produces the rainbow effect while revealing the brick motif. The distinction is not just the shape of the watch; the two lines put the colorful pattern on different components and create it by different methods.
Casio lists a 1/100-second stopwatch and countdown timer for both families. The 5600 specifications also include a multifunction alarm, flash alert, and LED Super Illuminator backlight. The 2100 specifications include hand shift, world time for 48 cities, five daily alarms, and a double LED Super Illuminator. These are manufacturer-listed functions, not independent test results. See Casio’s collection specifications.

Which Rainbow Brick Wall G-SHOCK has a metal bezel?
The stainless-steel-bezel models are GM-5600RW-1, GM-5600BRW-1, GM-2100RW-1A, and GM-2100BRW-1A. Casio says their metal bezels cover glass-fiber-reinforced resin cases; it describes the bezel production as forging, cutting, and polishing. The DW-5600RW-1 and GA-2100RW-1A are listed without the metal-bezel feature.
Choose between the GM and non-GM versions based on the bezel material and design you want. The available product information does not establish that one is more comfortable, more durable, or more legible than another.
Rank #3
- Metal-clad daring meets sophisticated gleam in this Casio G-Shock that delivers Smartphone Link via Bluetooth(R) and Tough Solar charging system, all in a meticulously finished metal design with iconic octagonal bezel
- This model features a blue metallic vapor deposition dial that is complemented by a black band made of environmentally responsible bio-based resin
What features do the watches share?
Casio lists shock resistance and 20-bar water resistance across the collection. The company also says key resin components in the case and band use bio-based resin. It does not provide a lifecycle figure that would quantify the environmental impact of that material choice. These are Casio’s stated specifications; they should not be read as independent verification.
