The Watch - A Review

Screen and Aesthetics

Casio’s F-91W is no head-turner. In fact, the design lacks essential aesthetics and comes with a simple digital display. The display is, however, clean and carries a minimalist design that still sells today. The accessory has stood the test of time and is the complete anti-matter to overly stylish wristwatches. It ranks as the most popular digital watch.

The acrylic crystal screen on this Casio watch comes with multiple hues of three different colors. Each color comes with blue accents and printed text for clarity. The model is cohesive in design and features an orderly display. The info is there, the time screams at you, and the watch does its job well.

Casio's brilliance comes into play with its ability to create a transparent display within a limited space. The display for Casio's F-91W is as clear as the Everest on a screen that is smaller than a small postage stamp. The high contrast digits improve visibility and allow users to screen the time from an arm's distance.

The wristwatch features a savvy backlight, which can give a soft green LED sign when pressed. The light is activated through a button press and fades into oblivion after a brief period.

The minimalist display and size of the Casio watch help provide optimal comfort and fit. The model doesn't slip across your wrist, even if you haven't tightened the notches. The lack of mass works in your favor, as the Casio wristwatch sits perfectly in position.

The rubber wristband cradles your wrist and makes the perfect fit. The company provides good value for money due to its cheap cost and slim design. The price is a little under $15.

Fit Quality

The Casio f 91w has the unique ability to fit on your wrist magically. The G-Shock resin strap can magically cradle your wrist and not let go of it, even if you are wearing a relatively loose fit. The digital display doesn't drag the modest masterpiece down your wrist and helps settle it in position.

The synthetic material creates a decent fit without breathing down into your wrist. However, some users report breathability problems with the watches.

The watch can accumulate sweat around the surface of the wrist it is in contact with.

The zero-breathability factor can become challenging to manage in humid or tropical temperatures. In this case, you would want to take off the watch and let your wrists breathe. The watches and the resin case can be hard to manage at times.

Interactivity

The Casio f 91w comes with an interactive display when needed. The watches may not be as interesting as smartwatches or the latest fitness trackers, but they do have some interactive features here and there.

The watch comes with a stopwatch feature to time your course or use it for other purposes. The feature can be activated through the stainless steel pushers or the right button. The stopwatch is accurate and provides precision to the point.

Additionally, there is an alarm mode, which can be activated through a few simple clicks of the button. The alarm mode is pretty comprehensive, and I found it interesting because it directly coincided with a similar alarm I had set on my cell.

The precision on the Casio f 91w was satisfying and provided good value for money due to its low price. The dark design won't make you forget Rolex and other premium brands, but it works well.

Additionally, the watch comes with hourly chimes to alert you of the passing hour. The chimes are heard through two simple bells, noticeable enough to alert you of the passing hour if you are wearing the watch on your wrist. The chimes are non-stop and will last for the duration of the watch's lifestyle.

Nothing fancy, but the Casio f 91w meets the bare minimum through its functional design, accuracy, and durability. The scratch-resistant design doesn't crash the gate and rush through it, but it strolls past in style, providing the bare minimum in style for your purchase. There is no reliable, better choice at this price.

Use in Water

The liquid resistance in Casio f 91w is often misunderstood. You can't jump into a swimming pool and expect the watch to work its magic. 

The watch is splash-proof, not abuse-resistant. Some reviewers complain about the watch not staying on after their hour-long stay in the swimming pool. Others complained about water droplets inside the watch a week after a dip in the pool.

The water-resistant feature works fine if you don't subject the watch to torment and abuse. The interface is fairly decent.

I wrote this review after a 15-minutes shower with the watch on. The Casio f 91w is reliable and performs well over time, and won't show signs of repair anytime soon.

Casio F91w Precision over the Years

Casio f 91w shares the same birthday as Taylor Swift and echoes a sync just as well as the singer's. We found the Casio 91w to be highly durable and perfect for combat.

The watch hasn't gone through innovation but sells for its accuracy, quartz movement, design, and ruggedness. Some believe it sells for its inexpensive nature, but what's a watch without precision?

Casio's F91w has only improved in precision over time. I timed the hour and alarm with the time on my phone, and the watch delivered perfect results for the most part. The hour and the alarm chimes are synchronous and work in congruence.

Conclusion

The watch will be the perfect addition to your collection. Even if you don't have one, the classic Casio works fine as a standalone accessory due to its decent battery life and digital LCD screen. Wear it to work, to the gym, and social events. The water-resistant watch won't turn heads but does its job well.
