Does your watch hit the desk or wrist rest when typing, or do your wrists tire during long keyboard sessions?
Here, I focus on thin, light models that address those desk-work concerns.
These 5 capable choices combine G-SHOCK's toughness DNA with remarkable thinness and lightness.
1. The Original and Ultimate Thin Square: CASIO GW-M5610U
Specifications:
12.7mm thick / approximately 52g / radio-controlled solar
Why I Chose It:
An essential choice for desk work: The King of Square G-SHOCK.
Its red frame and appearance matching the original G-SHOCK are also important attractions.
Despite offering radio-controlled solar, it weighs approximately 52g, reducing arm fatigue during long typing sessions.
The buttons sit recessed from the bezel, preventing accidental presses with the back of your hand during keyboard work—an excellent quality for desk workers.

Incidentally, if you do not need radio-controlled timekeeping and Tough Solar alone is enough, G-5600UE is recommended.

2. Almost No Sensation of Wearing It: CASIO F-91W, an Affordable Casio
Specifications:
8.5mm thick / approximately 21g / water resistant for everyday use
Why I Chose It:
A landmark affordable Casio.
Although it is not a G-SHOCK, it is exceptionally strong at eliminating physical interference during desk work.
The extremely light body, 8.5mm thick and just 21g avoids catching on cuffs or wrist rests, making it easy to forget you are wearing it.
Its toughness is modest, but it is worth owning if comfort during computer work is the priority.

3. Bluetooth in an Affordable Casio: F-B100W
[Specifications]:
8.8mm thick / approximately 26g / water resistant for everyday use
[Why I Chose It]:
It retains affordable Casio thinness and lightness while connecting through Bluetooth for automatic time adjustment, giving this affordable Casio functions that hardly feel inexpensive anymore.
It resolves the earlier Casio Standard weakness of lacking automatic time adjustment.
An excellent watch for computer workers who need accurate time.
It looks inexpensive but offers up-to-date, accurate time—a watch that can make you smile while wearing it.
A black negative-display model is also available, blending more naturally into the wrist.
4. A New Thin Analog-Digital Classic: CASIO GA-2100 or GA-B2100
[Specifications]:
11.8mm thick / approximately 51g / Battery-powered; B2100 has Tough Solar and Bluetooth
[Why I Chose It]:
An octagonal model that realizes the wish for a thin, light analog-digital watch.
As an analog-digital G-SHOCK, it offers remarkable thinness at 11.8mm, fitting exceptionally well under shirt and jacket cuffs.
The combination of digital display and analog hands suits quick, intuitive time checks between computer tasks.

5. Smart Pomodoro Focus: CASIO G-SQUAD GBD-200
[Specifications]:
15.0mm thick / 58g / smartphone connectivity
[Why I Chose It]:
It is somewhat thicker on paper, but flexible timer setup through a smartphone app is particularly powerful for desk work, including Pomodoro and interval timers.
You can program cycles of 25 minutes working and 5 minutes resting, or detailed timings, on a smartphone and manage them conveniently on your wrist.
Anti-slip slits on the back also help prevent a clammy wrist during long sessions in sweaty seasons.
