Casio
The one brand on this site with no specification table, and an explanation of exactly why.
By Sawyer V. · Published
The short answer
We publish no Casio specifications because Casio's US product pages do not serve their specification data to us, and this site does not publish figures it has not read on the manufacturer's own document. Casio's pages are fully readable in a browser, and we link them below.
Every other brand page on this site carries a specification table. This one does not, and the reason is procedural rather than editorial.
Casio's US product pages return an access-denied response to everything except an interactive browser. We were unable to read the specification data for any Casio reference, on any of Casio's regional sites, or through its support documentation.
Casio's pages are perfectly readable if you open them yourself. The links at the bottom of this page go straight to them, and checking the specification of a watch you are considering takes about a minute.
What we can say without a spec sheet
Some things about buying a Casio to keep do not depend on a specification table, and they are worth stating.
- The service model is different from every other brand here. Casio's digital and analog-digital watches are module-based. A module is replaced rather than rebuilt, which means there is no equivalent to a mechanical overhaul — and no service interval to plan for.
- The gaskets are still the wear item. Whatever the module does, a Casio's water resistance depends on rubber seals that harden with age, exactly like every other watch on this site. That is the maintenance a Casio actually needs, and it is the one nobody performs.
- Resin cases behave differently from steel. Resin does not corrode and does not dent, and it does degrade with UV exposure over many years. It cannot be refinished the way steel can.
- Battery access varies enormously by model. Some are a two-minute job at any shop; some require a specific back tool. It is worth checking before buying if you intend to own the watch for decades.
None of that is a specification claim, and all of it is checkable against Casio's own documentation, which is why we are comfortable publishing it.
How to assess a Casio yourself
Use the same six criteria we apply to everything else on this site, and read them off Casio's product page in a browser:
- The module number, which is Casio's equivalent of a caliber and determines what any repair involves.
- The water resistance rating, and whether it is a meter figure or a general statement. What each rating permits.
- The glass material — mineral is the norm at most Casio price points.
- The battery type and stated life.
- The case and band material, and whether the band is a standard width or a model-specific fitting.
- The stated warranty term.
Where Casio would sit on this site
Honestly, in the same conversation as the under $100 and under $200 tiers, and probably well within them — a module-based watch with no service interval has the same low-running-cost advantage that puts solar quartz so high on our lists.
We are not going to rank a brand we cannot cite. If Casio's specification pages become readable, this page will get a table and the date at the top will move.
What to buy instead, if you want a recommendation today
- A solar quartz field watch. The Timex Expedition Field Post Solar is 36mm with sapphire, 100m and no battery to change.
- A light-powered Citizen. The Chandler BM8180 is 37mm, 100m and warranted for five years.
- A 200m Eco-Drive diver. The Citizen Promaster BN0150 if you want something you will never maintain.
Questions people actually ask
Why are there no Casio specifications on this page?
Because Casio's US product pages do not serve their specification data to automated readers, and this site only publishes figures read from a manufacturer document we can link to. The pages are fully readable in a browser and we link them below.
Are Casio watches good?
We are not in a position to rank one, because we could not read the specifications. What we can say is that a module-based watch with no service interval has the same low-running-cost advantage that puts solar quartz high on our other lists.
Is a Casio a buy-it-for-life watch?
The module model means replacement rather than rebuilding, so it fails the strict rebuildability test — as does every quartz watch. On running cost it would likely score well. The maintenance a Casio actually needs is gasket replacement, and almost nobody does it.
Will you add Casio watches later?
If the specification pages become readable, yes — with a table like every other brand page here. Until then, publishing figures we have not verified would break the only promise this site makes.

Every specification and figure on this page came from one of these documents. Where a manufacturer does not publish something, the page says so rather than filling the gap.
