Design and Style
This comparison is really about philosophy.
The DW-5600 is a tool watch.
It is simple, clean and purpose-built. The square shape traces directly back to the original G-Shock design from 1983. Nearly every modern square G-Shock owes something to the DW-5600.
The DW-6900 is more emotional.
The large round face, three-eye layout and oversized proportions give it a very different personality. It looks like a G-Shock from across the room.
Many collectors consider the DW-6900 one of the most iconic G-Shock shapes ever produced.
The square is timeless.
The 6900 is legendary.
Winner: DW-6900 for style.
Comfort and Wrist Feel
This is where the DW-5600 starts pulling ahead.
The square is significantly smaller and lighter.
At only 53 grams, it disappears on the wrist after a few hours.
The DW-6900 is still comfortable, but the larger 67-gram case is much more noticeable. It sits higher on the wrist and takes up more space under sleeves.
Owners with smaller wrists often find the DW-5600 dramatically more comfortable.
For wrists under 7 inches, the difference can be significant.
Winner: DW-5600.
Features and Everyday Use
Functionally, these watches are extremely similar.
Both offer:
- Stopwatch
- Countdown Timer
- Multi-function Alarm
- Hourly Signal
- Auto Calendar
- EL Backlight
- Shock Resistance
- 200m Water Resistance
Neither watch has world time, Bluetooth or solar charging in its basic form.
The difference comes from operation.
The square’s larger display makes using timers and alarms slightly easier.
The DW-6900’s front light button is more convenient at night.
Winner: Slight edge to DW-5600.
Readability
This is one of the biggest advantages of the DW-5600.
The display is larger, cleaner and easier to scan quickly.
Whether you are checking the time while driving, exercising or working, the square layout simply works better.
The DW-6900 remains readable, but the round display sacrifices some screen space for style.
This is one of the most common reasons experienced G-Shock owners prefer the square.
Winner: DW-5600.
Backlight
The DW-6900 has one of the best light buttons Casio ever designed.
The large front-facing button is easy to find in the dark and easy to press while wearing gloves.
The DW-5600 uses a side button, which is functional but less convenient.
Many military users historically preferred the 6900 for this reason.
Winner: DW-6900.
Water Resistance
Both watches offer proper G-Shock-level water resistance.
As always, old gaskets, opened case backs and damaged buttons can reduce water resistance.
Winner: Tie.
Battery Life
Battery life is essentially identical.
Both watches are rated for approximately two years.
Many owners report longer real-world performance if the backlight is not heavily used.
Neither model wins here.
Winner: Tie.
Durability and Long-Term Wear
This category is extremely close.
The DW-5600 has one advantage: its smaller size means it bumps into fewer things.
The DW-6900 has another advantage: the bezel design protects the buttons exceptionally well.
Both are proven over decades of real-world abuse.
Construction workers, military personnel, mechanics, skaters and hikers have trusted both models for years.
There is no wrong answer here.
Winner: Tie.
Price and Value
The DW-5600 is usually the better value.
It often costs slightly less while delivering nearly identical functionality.
The DW-6900’s higher appeal comes mostly from design and collector culture.
If your goal is maximum functionality per dollar, the square wins.
Winner: DW-5600.
