Who needs the Apple Watch Ultra 4? I’ve been counting my steps and finding my phone with this cheap retro Casio digital watch, and I love it matt.evans@futurenet.com (Matt Evans) | usagoldmines.com

This year has been chock-full of great smartwatch releases: We’ve had the latest crops of Samsung, Google, Fitbit, and Amazfit watches. We had the Garmin Fenix 9 and Garmin Fenix 9 Pro at the high-end of the adventure watch category (and pricing range, some costing upwards of four-figure dollars or pounds), and soon the latest Apple Watches, with the Apple Watch Series 12 and (according to rumor) the Apple Watch Ultra 4.

However, I’ve had the most fun this year with a watch that costs just £55 (around $75 / AU$100).

The Casio F-B100W is a digital quartz watch which connects to your phone via Casio’s Mobile Link Bluetooth function, providing a handful of techy features. So I guess you could say it’s technically a smartwatch. Looks-wise, it’s very similar to the classic, outrageously cheap F-91W, only a little bigger and packing a fourth button on the side rather than the F-91W’s usual three.

The F-91W is beloved among watch nerds as a reliable, cheap ‘beater’ watch you can where anywhere. We’ve written about it in the past — it was worn by a young Barack Obama, due to its reliable timekeeping and seven-year battery life it was even used as a bomb timer by Al-Qaeda, and its got serious counterculture appeal due to its low-tech defiance of modern trends and the analog revival.

I’m a great advocate of having a ‘beater’ watch to throw on and wear during gardening, DIY, construction work or any time you want a break from your smartwatch. However, I’ve always thought the F-91W looked like a child’s toy on the average person’s wrist, with a tiny size of just 38.2 × 35.2 × 8.5 mm. The F-B100W is slightly bigger at 41.9 × 38.1 × 8.8 mm, a difference of less than 4mm, but it goes a long way towards feeling more like a watch.

It packs more features than the F-91W: as well as a timer, stopwatch, LED and alarm functionalities, it’s got dual-time zone features and some very basic fitness tracker functionality thanks to its Bluetooth capabilities: notably, a step counter.

Not only do your steps display on the watch’s LCD screen, but it also feeds your steps into the Casio Watches app, where you can see historic graphs of your steps across weekly and monthly views. In this way it acts as a virtual pedometer, just like the original Fitbit did before things got complicated. It also, unbelievably, has a Find My Phone feature, activated by holding the bottom-right button down.

And that’s it. It’s a stripped-down Bluetooth watch which looks like a classic Casio, with the most basic of fitness tracking functionalities, a useful Find My Phone feature and a two-year battery life. Reader, I am in love.

It’s an absolute belter of a watch for the price. I enjoyed taking it for a five-mile hike and watching my step count tick up, and it’s extremely light on the wrist at 26g. I’ve always liked the look of Casio watches, and as someone who perpetually misplaces almost everything I own, the Find My Phone feature is a near-essential tool. I like that it’s got a step counter broken down by graphs, but I also like that this is the only fitness tracking functionality it has, apart from the timer and stopwatch — which are in themselves ideal features for interval training, or timing rest periods in the gym.

In an era of all-singing, all-dancing smart technology that tracks everything, and often requires a subscription to sell your own data back to you, it reminds me of a simpler time in wearable technology. It’s not a great contributor to surveillance capitalism like lots of wearable tech these days (beyond having to make a Casio account): it’s just a fun digital pedometer, and is good value enough to be a ‘fun’ purchase for many people, rather than a serious investment.

It’s accurate, as you can set the time of the watch with your phone and the digital quartz movement is notoriously reliable, and will cost you nothing more than £55 (around $75 / AU$100) and a cheap watch battery every two years — a pack of 10 might run you about $5.99 / £4.99 / AU$8.99.

The F-B100W is sold out on Casio.com right now in the UK, and not yet available in the US, but keep your eyes peeled for restocks — this archaic-looking, secretly-smart digital watch is the stripped-back digital pedometer you never knew you needed.
