BRAND PORTRAITS / 03 / CASIO
Casio makes a compelling case for the watch as a useful instrument—and gives that instrument many different personalities.
To explore Casio, start with what you want to do: read the time quickly, run a timer, track another time zone or wear a watch with a particular design. That approach makes more sense than treating every digital watch, G-SHOCK and metal sports watch as a single category.
An electronics approach to the wrist
Casio’s first watch, Casiotron, used an automatic calendar. G-SHOCK followed in 1983, making resistance to impact a defining part of its identity. Together, these milestones help explain two recurring interests in Casio watches: useful electronic functions and designs built around a purpose. Sources: Casio in the 1970s and Casio in the 1980s.
A map beyond G-SHOCK
Use the official Casio watch directory to explore these starting points. Availability differs between regions, and the notes below are an editorial browsing guide rather than a specification for every model.
| Starting point | What to look at | What to compare |
|---|---|---|
| Casio digital watches | Display layouts and everyday functions | Digit size, illumination and button operation |
| G-SHOCK | Shock-resistant watches in many formats | Case shape, weight and exact feature set |
| Edifice | Sporting analogue designs | Dial readability and which functions you need |
| Pro Trek | Outdoor-oriented watches | Which sensors or functions the reference includes |
Why the module matters
The model name helps identify the watch you are buying. The module number helps you find the operating instructions. Before purchase, find out how to set the home city, switch daylight-saving settings and use any timer or alarm you care about. A feature that looks attractive on paper is less useful if you dislike operating it.
Do not assume two similar cases contain the same functions. Solar charging, automatic time synchronisation and phone connectivity must each be checked on the individual specification sheet. Our manual-finding guide explains how to locate the official instructions.
Casio lists Tough Solar power, a resin case and band, world time, alarms and a countdown timer for this model. It is one of the three watches in our solar comparison. Check the manufacturer’s product page for its complete specification.
Try the display, not just the case
When you handle a watch in a shop, look at it from the angle you normally use at a desk. Check whether you can read the time without moving your whole arm. Press the buttons you will use most often and try the light. For analogue-digital layouts, notice whether the hands obscure information you want to see.
Case length, thickness and strap shape deserve attention alongside diameter. A watch that looks compact in a photograph may sit differently from a round watch on your wrist. If you plan to replace a band, read our strap guide and verify the attachment: do not assume a generic strap will fit.
Who should start here?
Casio is a useful place to begin if your shortlist starts with functions and legibility. Choose a few features you genuinely use, compare two references, and keep the simpler option in consideration. The right Casio is the one whose controls, display and fit make sense in your day.
