Casio Watches

Casio Watches

Casio might just be the most democratic watch brand on Earth.

From the $10 F91W to $1,000+ G-Shock Master of G series, Casio covers every wrist, every budget, and just about every function imaginable — and does it with more authenticity

than most brands three times the price.

You don’t buy a Casio to flex. You buy one because it works. And if you’re paying attention, you might also realize just how much collector respect it commands.

A Little History

Casio started in Japan in 1946, originally building calculators and electronics. In 1974, they launched the Casiotron — one of the first digital watches with an

automatic calendar function.

From there? Casio led the digital quartz revolution, releasing icons like:

  • F91W — the no-frills digital that’s been in continuous production since 1989

  • G-Shock DW-5000C (1983) — designed to survive a 10-meter drop, 10-bar pressure, and 10-year battery life

  • Databank series — calculator watches, schedule trackers, and nerd-culture staples

  • Pro Trek — outdoor and hiking watches with altimeters, compasses, and solar charging

  • Oceanus and Edifice — sleek analog-digital hybrids and solar chronographs for the enthusiast crowd

Casio became synonymous with durability, functionality, and affordability — and somehow, also cool.

What Collectors Love

Casio is a rare brand that manages to be ubiquitous and still collectible.

Collector favorites include:

  • G-Shock “Square” models — especially the metal-cased GMW-B5000 series and vintage 5600 variants

  • Master of G (Frogman, Rangeman, Mudmaster) — purpose-built, oversized beasts for extreme environments

  • Frogman ISO-certified divers — the only true dive-rated G-Shock

  • Vintage calculator watches and early LCDs — especially pre-1985 pieces

  • Limited collabs — including NASA, BAPE, John Mayer, and Japanese domestic market (JDM) exclusives

There’s a whole subculture of Casio modding, too — with collectors customizing straps, bezels, and even internals. The G-Shock universe runs deep.

Why Casio Deserves Respect

Because it democratized horology — and never stopped innovating.

Solar charging. Bluetooth. Atomic timekeeping. GPS. Triple sensor tech. Casio builds some of the most advanced watches on the planet, and sells them

for a fraction of what they’re worth in engineering.

And even their simplest watches? Still tough, still accurate, and still made with more thought than most luxury quartz.

Whether you're ten years old or a ten-watch collector, Casio belongs in the lineup.

What’s Out There Now

Casio’s lineup is massive, but the main categories are:

  • G-Shock — digital, analog-digital, tactical, dressy, and mod-friendly. Tough as ever.

  • Pro Trek — outdoor adventure watches with solar power, compasses, barometers, and altimeters.

  • Edifice — sporty analog chronographs, often solar and Bluetooth-enabled.

  • Oceanus — Japan-only premium line: titanium cases, sapphire crystals, multiband sync.

  • Vintage and Retro — including F91W, A158, and databank reissues

The secondary market is full of rare G-Shocks, discontinued Pro Treks, and cult-favorite editions. Prices range from $20 to $2,000+ — and every level has its fan base.

Fed’s Take

I’ve said it before: every collector should own at least one Casio.

Whether it’s a beat-up F91W, a fully kitted Frogman, or a sleek Oceanus that punches way above its weight — there’s just something honest about Casio.

They build watches that work. That last. That do more than most watches ever will.

And they’re fun. That matters.
