For G-SHOCK, "red" is not just a color. It is a symbol color that has embodied the brand identity since its birth in 1983. The DW-5600RRB-4DR, one of the models in the "Iconic Styles" series, is a model that brings out this commitment to red to the fullest.The contrast created by the red band and bezel and the black inverted LCD is a model that stands out overwhelmingly.
The square form of the 5600 series can be said to be the origin of G-SHOCK. A presence that makes a statement in the city, outdoors, and in sports scenes. And for 14,850 yen, this watch is packed with eco-friendliness by using biomass plastic for the bezel and band—this is the true value of G-SHOCK's cost performance.

■ What is Iconic Styles? G-SHOCK's identity in red
G-SHOCK's "Iconic Styles" is a series that focuses on the brand color red. It's not just a red G-SHOCK, but the combination with the inverted LCD and black accent color maximizes the strength and design characteristic of G-SHOCK.
DW-5600RRB-4DR is a model based on the 5600 series. This Iconic Red coloring is applied to the most basic form that is the origin of G-SHOCK. Whether as an accent to street fashion or as a landmark in sports scenes, there are few models that can stand out from the crowd when it comes to attracting attention when worn.
■ Inverted liquid crystal x red ─ A design that combines strong appearance and practicality
The dial of DW-5600RRB-4DR is an inverted liquid crystal. The display is inverted from a regular LCD display, with white numbers appearing against a dark black background. This inverted liquid crystal combined with the red band and bezel creates a strong contrast between black and red.
In terms of visibility, the inverted LCD has high contrast and is effective in attracting the eye. Equipped with LED backlight (super illuminator) and afterglow function, there is no problem with visibility in dark places. The audible flash function lights up in conjunction with alarms, timers, and time signals, and when combined with this red color, it has even more presence.
■ Adoption of biomass plastic ─ G-SHOCK's approach to the environment
The main resin parts of the bezel and band are made of biomass plastic. This material, which is made from renewable, plant-based organic resources, is expected to have a lower environmental impact than conventional petroleum-based plastics. The hidden highlight of this model is that it shows consideration for the environment through the selection of materials while maintaining the "toughness" typical of G-SHOCK.
These efforts demonstrate G-SHOCK's attitude, and the casual design contains messages that are relevant to the times.
■ 5600 series functions ─ Contains all G-SHOCK standards
The installed functions are firmly in line with G-SHOCK standards. The stopwatch measures 1/100 seconds and is a 24-hour meter with a split function. Timer supports up to 24 hours and auto-repeat. It is equipped with one multi-alarm, an hourly signal, and a fully automatic calendar, and the battery life is approximately 5 years.
The shock-resistant structure (shock resist) makes it resistant to drops and impacts, and the 20 ATM water resistance makes it suitable for swimming and water sports. Accuracy is an average monthly difference of ±15 seconds. The sense of security that ``If you buy a G-SHOCK, you can do anything'' remains the same with this model.

■ Buyer's comment
Every time G-SHOCK's Iconic Red series comes out, I always think, ``This color is really strong.'' This DW-5600RRB-4DR brings full red to the simple square form of the 5600, making the color stand out because there are no unnecessary elements. I particularly like how it goes with the inverted LCD, and the combination of white text and red band on a black background attracts the eye. I also like the use of biomass plastic, which gives it the feel of a ``G-SHOCK suited to the times.'' At 14,850 yen, I think this impact is the best value for money.
