Frequently Asked Questions
How accurate is the timekeeping on the Casio F91WG-9?
The Casio F91WG-9 is powered by the Japanese quartz Calibre 593 movement. It has a rated accuracy of approximately +/- 30 seconds per month under normal operating conditions. This level of precision is standard for this type of reliable digital watch.
How does the stopwatch (chronograph) function work?
The watch includes a 1/100-second digital stopwatch with a measuring capacity of 59 minutes, 59.99 seconds. It features elapsed time, split time, and 1st-2nd place time modes. You can operate it using the buttons on the side of the case.
What is the battery life, and what kind of battery does it use?
The Casio F91WG-9 uses a CR2016 battery. Under typical usage conditions, including one alarm operation and one light operation per day, the battery is estimated to last approximately 7 years. This long battery life is a key feature of the watch.
Is this watch waterproof? Can I swim with it?
The watch has a water resistance rating suitable for everyday use, which means it can withstand minor splashes and rain. It is not designed for swimming, showering, or diving. Submerging the watch in water should be avoided to protect the internal module.
How will this watch fit on a small or large wrist?
With a case size of 37.5mm wide and a very slim profile, the F91WG-9 is designed to be a comfortable fit for a wide range of wrist sizes. Its lightweight resin construction makes it unobtrusive for all-day wear. The resin strap is adjustable to accommodate both smaller and larger wrists.
Does the watch have a backlight for night viewing?

Editor's take
The Casio F91WG-9QDF stands as an enduring icon of accessible digital watchmaking, a testament to Casio's legacy of combining utility with distinctive design. This model, with its instantly recognizable silhouette and gold-toned digital display, appeals to those seeking a blend of nostalgia and straightforward functionality. It's a perfect entry point for anyone appreciating the simplicity and reliability that defined a generation of timepieces.
At its core, the F91WG-9QDF is powered by a robust Japanese quartz movement, ensuring precise timekeeping with minimal fuss. The lightweight resin case and strap contribute to its comfortable wearability, making it almost imperceptible on the wrist. Essential features like a daily alarm, a 1/100-second stopwatch, and an auto calendar are all easily accessible, highlighting the watch's practical design. The long-lasting CR2016 battery offers an impressive approximate 7-year lifespan, reducing the frequency of maintenance.
While the F91WG-9QDF excels in its core functions and retro charm, its 30m water resistance means it is only suitable for splashes and light rain, not for swimming or showering. Enthusiasts looking for more advanced features, such as multiple time zones, solar charging, or robust shock protection beyond its inherent durability, might find this model too basic. Its resin construction, while lightweight, also lacks the premium feel of stainless steel or more exotic materials.
Ultimately, the Casio F91WG-9QDF is recommended for individuals who value a no-nonsense, reliable digital watch with a strong retro aesthetic. It's an excellent choice for casual daily wear, a first watch for a younger enthusiast, or as a fun, affordable addition to any collection. For those seeking a more rugged or feature-rich digital experience, exploring Casio's G-Shock line might offer suitable alternatives.
