Casio F-91WPC-1A
The F-91 I Couldn't Bring Myself to Sell
Anyone who has followed The Casio Collector for a while will probably know that I have a bit of history with the F-91W.
At one point I owned 25 of the 26 variants of the F-91 range. Eventually I made the decision to sell the collection and keep the original F-91W-1 – the classic black model that started it all for me.
Well... that was the plan.
There were a couple I simply couldn't bring myself to part with, and the
Casio F-91WPC-1A PAC-MAN was one of them.
Released as part of Casio's PAC-MAN collaboration in 2024, this little watch takes one of the most recognisable digital watches ever made and combines it with one of the most recognisable video games ever made.
And somehow, it just works.
Two Icons Brought Together
The standard F-91W doesn't need much of an introduction.
It's simple, cheap, lightweight, instantly recognisable and has remained fundamentally unchanged for decades. There are watches with far more features, but very few have achieved the same status.
PAC-MAN is much the same.
Casio created this collaboration as part of its celebration of 50 years of Casio watches, while also lookingahead to PAC-MAN's 45th anniversary in 2025.
Putting the two together therefore feels surprisingly natural.
What I particularly like is that Casio hasn't tried to completely reinvent the F-91W to make the collaboration work.
Underneath the PAC-MAN graphics, this is still very much an F-91.
PAC-MAN Without Going Overboard
The biggest difference is obviously the face.
PAC-MAN appears alongside the four ghosts – Blinky, Pinky, Inky and Clyde – with vivid neon colours surrounding the familiar digital display.
Against the black resin case it looks brilliant.
It's colourful and unmistakably PAC-MAN, but it hasn't completely overwhelmed the original F-91 design. You can still look at it from across the room and immediately recognise what watch you're looking at.
There are some lovely smaller details too.
The strap keeper carries the familiar “WAKA WAKA” reference, while the stainless-steel caseback is engraved with the PAC-MAN character and logo. Casio even gave the collaboration its own neon-themed special packaging.
They're little touches, but they're exactly the sort of details I want from a collaboration model.
Still an F-91W at Heart
Turn away from the PAC-MAN graphics and there's nothing complicated going on here.
And that's a good thing.
You still get the familiar 1/100-second stopwatch, daily alarm, hourly time signal, 12/24-hour display and basic calendar.
The backlight is the traditional green LED rather than anything particularly sophisticated.
Is it the greatest backlight Casio has ever fitted to a watch?
Absolutely not.
But changing it would almost feel wrong at this point.
The simplicity is part of the F-91W's identity.
Press the button, one side of the display lights up green, you read the time and get on with your life.
Ridiculously Easy to Wear
Another reason the F-91W has survived for so long is simply how comfortable it is.
The F-91WPC-1A weighs only 21 grams and measures 38.2 × 35.2 × 8.5 mm.
In a world where watches seem to have become progressively larger and heavier, putting an F-91 on the wrist is almost refreshing.
It practically disappears.
The PAC-MAN version also uses a bio-based resin band, made using renewable organic resources as part of Casio's efforts to reduce environmental impact.
Whatever you think about the environmental side of it, on the wrist it still feels exactly as an F-91 should – light, simple and comfortable.
Seven Years From a CR2016
Power comes from the familiar CR2016 battery, with Casio quoting approximately seven years of battery life under its specified usage conditions.
That's one of those specifications that barely seems remarkable on a Casio because we've become so accustomed to it.
Seven years from a tiny coin cell in a watch weighing 21 grams is pretty bloody good.
There's no solar charging, Bluetooth or clever power management to think about.
Fit a battery, set the time and forget about it for years.
Sometimes simple really is better.
Why This One Survived the F-91 Clear-Out
This is probably the most important part of the review for me.
When you've collected as many variations of one watch as I did, eventually you have to ask yourself whether you're keeping them because you genuinely love every individual watch or simply because you're trying tocomplete the set.
For me, I genuinely wanted the whole set, and I thought I had done at one point, but then found out there was another, the Tiffany Blue F-91WB-2A2, however, I was never going to pay the £300+ price tag people were wanting for it.
So I sold most of them.
The original F-91W-1 had to stay. If I was only going to own one F-91, that was always going to be it.
Except apparently I wasn't only going to own one.
The PAC-MAN was different enough that I couldn't bring myself to let it go.
It isn't just another colour variation. It has its own identity and represents a genuine collaboration between two names that instantly bring back memories of simple digital technology.
There's also something wonderfully unnecessary about it.
Nobody needed a PAC-MAN F-91W.
I'm just glad Casio made one.
The Same Watch, Completely Different Personality
That's probably what Casio does best with the F-91.
The basic watch underneath hardly changes, yet a few alterations to the colours and graphics can give it acompletely different personality.
The standard black F-91W-1 is understated and utilitarian.
This one isn't.
The neon graphics immediately catch your eye, and the PAC-MAN characters turn an incredibly familiar watch into something playful.
Yet it hasn't lost what makes the F-91W appealing in the first place.
It's still cheap to run, incredibly light, simple to use and comfortable enough to wear all day.
It's an F-91W having a bit of fun.
And I'm completely fine with that.
The Casio Collector Verdict
The Casio F-91WPC-1A PAC-MAN was one of the few F-91 models that survived when I decided to break up my collection.
That probably tells you most of what you need to know.
There are more capable Casios in my collection. There are tougher Casios, more valuable Casios and watches with considerably more technology inside them.
But that's never really been the point of the F-91W.
Its appeal comes from simplicity.
The PAC-MAN collaboration takes that familiar formula and adds just enough personality to make it feel genuinely special without ruining what made the original watch so good.
I love the neon face. I love the tiny WAKA WAKA detail. I love the engraved caseback.
And most importantly, I still love that underneath all of it sits a good old-fashioned F-91W.
I sold almost my entire F-91 collection.
This one wasn't going anywhere.
