The Casio F 91w is a retro style timepiece with that classic Casio rectangular build and digital display. It’s also got quite a lot of handy features that I’ll look at in some detailing later on.

Casio F-91W Design And Build Quality
The Casio F-91W was introduced in 1991 and is still in high demand to this day due to its popularity for the simplistic design that’s reliable and unpretentious, it simply does the job you need it to. The watch has a retro feel to it, of course now being over 25 years old itself. The casing is made of a plastic resin mix giving it this lightweight feel, easy on the wrist. At the end of the day, for a watch to remain this popular over such a long time frame, it must be well made, and it is.
Casio F 91W Dial
The dial is pretty simple in keeping with the whole ‘straight to the point’ design of the watch. It’s a digital dial with a back light feature to illuminate the watch in dark conditions, making it easy to read. The LCD digital screen showcases all the information for the extra features of the watch too, these I’ll point out later on.
Casio F 91W Sizing
Being an older watch it features a smaller design that some of these modern timepieces we say around today. The case width is approximately 37mm and has a case thickness of 9mm. It’s classed as a unisex watch but it’s worth noting that 37mm is going to look a little big on some women’s wrists. Overall though it’s proved an ideal size for many, it sits nice and flat on the wrist and isn’t overly in your face at all.
Casio F-91W Crystal
This Casio watch features a pretty basic acrylic glass. It’s no surprise to see this really, we’re looking at a very affordable watch, and when it comes to keeping costs down, using an acrylic glass is a decent way to achieve this. Whilst I’m not often a fan of acrylic glass, I think it’s perfectly accepted in this case, with the whole design and pricing in mind.
Strap & Clasp
The strap of the F 91W is made of rubber which is a lightweight, comfortable option for many. The strap itself is a pretty good medium thickness in my opinion, and has a width of 15mm. There’s no extras bells or whistles to the strap, it’s just a simple easy to use design aimed at comfort and durability.
Casio F-91W Water Resistance
The Casio F-91W features a really basic water resistance rating of 30m also known as 3 bar. Now 30m water resistance really isn’t much, but I’m sure many people won’t be too surprised considering the cost and all. This 30m rating makes the watch suitable for everyday use. Splash/rain resistant. Not suitable for showering, bathing, swimming, snorkelling, water related work and fishing.
The thing with water resistance testing is that it’s done in a still environment with no added pressure. So 30m resistance doesn’t mean you can take it 30m deep. The very motion of moving your arm would increase the pressure forced upon a watch greatly from that that it would experience just submerged.
Casio F-91W Caseback
The caseback of the Casio F 91W is pretty basic. It’s a screw down stainless steel case back with some basic produce details along with the word ‘Casio’ engraved on the back.
The Casio F-91W Movement
The watch is powered by a reliable Japanese quartz movement. This gives the watch accurate timekeeping losing at most around 30 seconds in any given month. Powering the quartz movement is a CR2016 3 volt lithium button battery which gives the watch an average 7 years worth of usage, depending on how often you use the back light and alarm function.
Casio F-91W Extra Features
The F91W has a stopwatch function that can time up to 59:59:99, just below an hour. It can also mark net and split time for lap timing. Another useful feature is the alarm function, this can give you an hourly time beep or a single daily alarm that lasts 20 seconds. There’s also an automatic calendar, although it’s not quite to the same standard as modern ones. This calendar adjusts for the varying amount of days in each month, but can’t account for a leap year as it doesn’t track the year. Last but not least is the backlight feature. A green LED is located to the left of the display, it’s not overly bright or evenly distributed but it does provide enough light to read the screen.

A final Word On The Casio F-91W
So there you have it, a fairly detailed look at the Casio F-91W.It’s no surprise to me why this has proved to be such a timeless popular watch. A lot of people are switching to this retro style with a no fuss attitude, and the Casio F-91 provides just that.
