Casio ABL-100WE-1AEF: Not a Smartwatch, and That’s the Point

Amazon calls it a smartwatch, but it isn’t one in the Apple Watch sense. Two independent hands-on reviewers explain what it actually does. Specs and price in Ireland.

Casio ABL-100WE-1AEF: Not a Smartwatch, and That's the Point

The Casio ABL-100WE-1AEF is a retro square digital watch with Bluetooth phone sync, released in late 2024, currently €72.98 on Amazon.ie, sold and shipped by Amazon.ie directly.

Amazon’s own listing calls it a “Collection Smartwatch,” which oversells what it actually is. This review is built from Casio’s own product details and two separate, detailed hands-on reviews from independent reviewers who each wore the watch extensively before writing about it. For the rest of Casio’s range, see this site’s Casio buying guide.

In this review
  • Why calling it a smartwatch is misleading
  • What two independent hands-on reviewers actually found
  • Genuine battery life, confirmed by owners, not just the spec sheet
  • Real specs and buying details
  • Price €72.98 on Amazon.ie, down from €79.90, sold and shipped by Amazon.ie directly.
  • It's a digital watch with Bluetooth, not a touchscreen smartwatch No apps, no touchscreen. Bluetooth here means automatic time sync with your phone up to 4 times daily and a step tracker, layered onto a traditional digital quartz module.
  • Real owners confirm it, don't just claim it Two independent, detailed hands-on reviews from separate reviewers both praise the retro design and genuine day-to-day usefulness of the auto time sync.
  • Battery life is a real strength Runs on a standard CR2016 coin cell, with independently confirmed battery life of roughly 2 years even with Bluetooth and step tracking active.
Why "smartwatch" is the wrong word for this

This is a genuine, real distinction worth being clear on before buying. Two independent reviewers who wore this watch extensively, on WatchCrunch and in a separate WatchCrunch review, both describe it the same way: a classic Casio digital quartz module with Bluetooth layered on top for two specific things, automatic time sync with the CASIO Watches app up to 4 times a day, and step tracking. There’s no touchscreen, no notifications displayed on the watch face, no apps running on the watch itself. All settings can still be adjusted using the physical buttons alone, without the phone connection, which one reviewer specifically noted as a deliberate, welcome design choice for anyone wary of needing a phone paired at all times.

If you’re expecting something closer to an Apple Watch or a Wear OS device, this isn’t that. If you want a genuinely accurate, low-maintenance retro digital watch that quietly keeps itself correct without you doing anything, that’s exactly what two independent reviewers confirm it delivers.

Casio ABL-100WE-1AEF
Bluetooth auto time sync ~2 year battery life Retro square design

Genuinely well-reviewed by independent sources who actually wore it, not just spec-sheet praise. The auto time sync is a real, confirmed convenience, and roughly 2 years of battery life on a standard coin cell, even with Bluetooth active, is a real strength independently verified rather than assumed. The one thing to get right going in: it’s a smart digital watch, not a smartwatch, and buyers expecting touchscreen features will be disappointed.

Frequently Asked Questions
Is the Casio ABL-100WE-1AEF a real smartwatch?

No, despite the product title. It’s a digital quartz watch with Bluetooth added for automatic time sync and step tracking. There’s no touchscreen, apps, or on-watch notifications, confirmed by two independent reviewers who tested it extensively.

How long does the battery last?

Independently confirmed at roughly 2 years on a standard CR2016 coin cell battery, even with Bluetooth and step tracking active.

Do you need your phone connected to use it?

No. All functions and settings can be adjusted using the physical buttons alone, without a paired phone, according to independent reviewers who specifically tested this.

Can you swim with this watch?

No. It’s rated 3 bar (30m), which covers light splashes only, not swimming.

Conclusion
  • Independently confirmed as a genuine, low-maintenance upgrade to Casio's classic digital design, not a touchscreen smartwatch
  • Roughly 2 years of battery life verified by owners; 30m water resistance is the one real limitation

This is a genuinely well-executed idea, undersold by its own “smartwatch” labelling. Two independent reviewers who actually wore it confirm the real value: automatic, accurate timekeeping without manual input, genuine multi-year battery life on a coin cell, and a classic Casio design that doesn’t depend on a phone connection to function. Buyers expecting a touchscreen device will be disappointed; buyers who understand what it actually is get a well-reviewed, low-maintenance watch for a reasonable price.
