F105 boasts a basic alarm but has a dimmer backlight. F91W shines brighter with its backlight but lacks an alarm.
Introduction
In the realm of affordable and reliable timekeeping, two Casio’s reign supreme: the F105W and the F91W. Both have carved a niche for themselves, becoming iconic for their simple functionality and timeless design. But with seemingly minor differences, choosing between the F105 and F91 can be a head-scratcher.
This comprehensive guide dives deep into every aspect of these two Casio titans, equipping you with the knowledge to make an informed decision.
Casio’s F-series watches have become synonymous with practicality and affordability. The F91W, released in 1989, quickly rose to fame for its durability and unbeatable price tag. Nicknamed the “Classic” or the “Casio Calculator Watch” due to its digital display’s resemblance to a calculator screen, it became a go-to for students, athletes, and anyone needing a reliable timepiece.
The F105W followed suit in the early 1990s, building on the F91W’s success by adding a basic alarm function. However, it retained the core features that made its predecessor so popular. Today, both watches remain mainstays in Casio’s lineup, catering to users who prioritize practicality and value.
History
The Casio F91W’s story began in 1989. Its simple design, durability, and water resistance made it a global phenomenon. Imagine classrooms filled with students sporting the now-iconic black-and-white digital display. The F91W transcended timekeeping, becoming a cultural symbol of practicality and affordability.
The F105W, introduced a few years later, continued this legacy. While it retained the core features of the F91W, the addition of a basic alarm function offered users a slightly more versatile option.
Technical Breakdown
Despite their similar appearance, there are some technical distinctions to consider when choosing between the F105 and F91W.
Movement:
Both watches utilize a highly reliable quartz movement. This electronic movement ensures accurate timekeeping, making them perfect for everyday wear. You can expect them to gain or lose only a few seconds per month, keeping you on top of your schedule.
Materials and Construction:
Durability is a hallmark of both F105 and F91W. They share a lightweight and comfortable resin case that can withstand everyday bumps and scrapes. The plastic straps, known for their flexibility, ensure a comfortable fit on your wrist.
Both watches boast water resistance up to 30 meters. This means they can handle splashes, rain, and shallow submersion. However, they’re not ideal for activities like swimming or diving.
Functions and Features:
Here’s a table summarizing the key functions and features of each watch:
| Feature | Casio F105W | Casio F91W |
|---|---|---|
| Timekeeping | Yes (12/24 hour format) | Yes (12/24 hour format) |
| Daily Alarm | Yes (one alarm) | No |
| Hourly Signal | No | No |
| Stopwatch | No | No |
| Countdown Timer | No | No |
| Electro-Luminescent Backlight | Yes | Yes |
| Water Resistance | 30 meters | 30 meters |
As you can see, the main difference lies in the inclusion of a basic alarm function in the F105. This can be a valuable addition for those who need a reminder to wake up, take medication, or meet deadlines.
Design and Aesthetics
Dial Design:
The F105 sports a dark blue dial with a prominent “Illuminator” text positioned above the digital display. This adds a touch of color and might appeal to those who prefer a more contemporary look.
The F91W opts for a classic black-and-white display with a subtler layout. This timeless design has become synonymous with the F-series and might resonate with those who appreciate a more traditional aesthetic.
Case and Bracelet:
Both watches have a similar black resin case design. However, the F105’s case might feel slightly larger due to its more pronounced bezel around the display. This could be a factor for users with smaller wrists who prefer a more streamlined profile. Conversely, users with larger wrists might find the F105’s slightly bigger size offers a more balanced and proportional look.
Ultimately, both watches remain comfortable for everyday wear due to the lightweight resin construction. However, trying on both options in person is recommended to determine which case size feels most comfortable and visually appealing on your wrist.
The black resin straps are identical on both watches, ensuring a comfortable and lightweight fit. However, some users might find the plastic material a bit too lightweight and prefer a more substantial feel offered by metal or leather straps. Luckily, the standard size of the straps (typically 18mm) allows for easy replacement with aftermarket options.
Brand Image:
Both watches exude a retro-casual vibe that’s become synonymous with Casio’s F series. They evoke a sense of nostalgia and practicality, making them a popular choice for those who appreciate a timeless design.
The F91W, with its longer history and cultural significance, might hold a slightly more “iconic” status. Its black-and-white display has been ingrained in popular culture for decades, making it instantly recognizable.
Ultimately, the design choice boils down to personal preference. The F105 offers a more contemporary aesthetic with its blue dial, while the F91W maintains a classic look. Consider your personal style and what kind of vibe you want to project with your watch.

Common Problems

Readability: The small digital display might be difficult to read for users with poor eyesight. The simple design prioritizes functionality over aesthetics, and the digits might appear small for some users.
