Here is an in-depth review of the noteworthy GW-BX5600-1, released in November 2025.
To give the conclusion upfront,
this is the ultimate natural evolution of the 5600 series.
Design, legibility, and functions all move up 1 level, delivering exceptional satisfaction in daily use.
Comparing it with the popular GW-M5610U and DW-5600UE, this article explains
why the GW-BX5600-1 is a leading choice for 2025
in detail.
◆What Is the GW-BX5600-1?

Based on the original square design inherited from the early 5600 series,
it packs in the latest G-SHOCK technology as an evolved 5600 series model.
Particularly notable points include:
- MIP LCD, a first for the 5600 series
- Automatic time synchronization through Bluetooth
- Improved legibility and usability
- Higher performance while retaining a lightweight resin design
- The most fully featured model with the 5600 design in the current lineup
With so many structural refinements, calling it the ultimate everyday 5600 feels appropriate.
A Treat for 5600 Fans: An All-Functions Model Finally Arrives!
Until now:
- 5600 series = battery-powered models
- 5610 series = solar with radio-controlled timekeeping
- 5000 series = flagship models
This was the unwritten hierarchy.
First, representing the 5600 series is the DW-5600E = battery-powered, without radio-controlled timekeeping

Next, representing the 5610 series is the GW-M5610 = radio-controlled timekeeping and Tough Solar, eliminating routine battery replacement

Then, representing the 5000 series is the GMW-B5000D = made in Japan, screw-back case, radio-controlled timekeeping and solar power

Thus, the 5600 series had become associated with batteries only and no radio-controlled timekeeping.
Until now, fans of the 5600 design could feel slightly shortchanged.
The 5600 design is very cool too…
But the newly released GW-BX5600
keeps the 5600 design while including all the latest technology: radio-controlled solar, Bluetooth, and an MIP LCD
—the model 5600 fans have awaited for years!
Personally, I am very happy to see the latest functions in the same 5600 design.
It is a long-awaited model for fans of the 5600 family.
◆Design: The Original Shape with More Modern Precision
The GW-BX5600-1
combines the original DW-5600's rugged character with the sharp finishing of current models.
▶A Clean Square Design
The characteristic 5600 square shape remains.
Look closely, though, and
- the bezel edges
- the dimensional dial frame
- the elastomer finishing on the sides
are carefully refined, so it looks cleaner despite showing more information than earlier 5600 models.
▶A Different Look by Day and Night
The MIP LCD displays beautifully in outdoor light and looks cool with an understated black appearance indoors.
Its appearance changes with the setting, adding the appeal of long-term enjoyment without growing tired of it.

◆Legibility: Finally Overcoming the 5600's Biggest Weakness
The 5600 series' weakness was a dark LCD and poor off-angle legibility.
But this time…
✔A Different Level of Legibility with MIP
The MIP LCD is a high-definition display that remains easy to read in direct sunlight and from an angle, with greatly improved legibility over earlier LCDs.
- Clear display in sunlight
- Readable from the side
- Legibility maintained even with more information
- Easy-to-read timer and World Time
It is surprising how readable a 5600 series model can be.
For example, this photo from Casio's official website shows the GMW-BZ5000D-1, which uses the same MIP display.
👆You can read the LCD even from this angle.
In contrast, my G-SHOCK with a conventional negative LCD…
👆It is unreadable… This is why some people avoid negative LCDs.
With MIP, however, you can read it clearly.
This time, you should have no regrets about choosing a negative display!

✔2 Font Choices
- Standard font: sharp and modern
- Classic font: retro 7-segment display that suits a square
My impression is that many 5600 fans choose the classic font.
A 7-segment display refers to
a font that creates numerals by combining 7 straight segments, as used in traditional digital watches and calculators.
Its angular appearance
works beautifully with G-SHOCK's classic square digital design,
with a retro feel, ruggedness, and clear legibility.
Meanwhile, the new Standard font
uses smoother, rounder, more modern numerals that are also easy to read.
Choose 7-segment for the feel of the original G-SHOCK,
or the new font for a more futuristic appearance.
◆Functions: A Complete Package with Little to Complain About
The GW-BX5600-1 is closer to a near-flagship than a midrange model.
- Bluetooth automatic synchronizationKeeps time accurate when a smartphone is nearby
- Multi Band 6Radio signal reception
- Tough SolarNo worry about a dead battery
- Alarm / Countdown timer / Stopwatch / World Time
- LED backlight, subdued and easy to read
The backlight in particular has
a more subdued, gentler brightness than the GW-M5610U, which is a welcome benefit that reduces eye strain at night.
◆Weight and Comfort: Optimized for Everyday Wear
Lightness is part of the 5600's appeal, and that advantage remains here.
- Resin bezel
- Resin band
- Much lighter than metal models
It is comfortable over long periods, offering
the versatility to leave it on for work, exercise, and sleep.
Its smoother case-back finishing also feels very good against the skin.
Some composite bands originally sold for the 5600 family now carry sellers' notes saying they can also be used on the GW-BX5600.
If you prefer a three-fold clasp band, consider buying one.
The appearance and wearing comfort change completely.
Worth considering as a customization option when you want a change from the original band.
