Casio F-91WF: The Iconic Watch Gets a Hiking Upgrade! (Fabric Strap Review) (2026)

Casio's F-91W has been a beloved timepiece since its inception in 1989, renowned for its simplicity and practicality. However, the standard resin strap has always been a point of contention for outdoor enthusiasts, as it can become sweaty and uncomfortable during long hikes. Casio has addressed this issue with the introduction of the F-91WF, a fabric-strap variant that promises to breathe better on the wrist during extended outdoor activities.

The F-91WF is a subtle yet significant upgrade, offering a more practical alternative to the original resin strap. The woven fabric strap is a simple change, but it makes a world of difference in terms of comfort and functionality. Personally, I think this is a brilliant move by Casio, as it caters to a specific need of outdoor enthusiasts without compromising the core features of the F-91W.

The F-91WF retains the core specs of its predecessor, including the digital module, resin case, and compact proportions. It is available in three colors: black, navy, and olive drab green, and is water-resistant to 30 meters. The watch runs on a single CR2016 battery, which is rated for seven years of life, and offers stopwatch, daily alarm, and auto-calendar functions.

While the F-91WF may not be the most feature-rich digital hiking watch on the market, it offers a unique blend of simplicity, comfort, and practicality. In my opinion, it is a perfect companion for casual hikers and outdoor enthusiasts who value functionality and style.

However, it is worth noting that the F-91WF is expected to cost more than the standard F-91W, which typically retails for under $30. In Thailand, the fabric-strap variant is priced at around $48, which is double the price of the standard model. This price difference may be a barrier for some consumers, but I believe it is a small price to pay for the added comfort and functionality.

In conclusion, Casio's F-91WF is a welcome addition to the F-91W lineup, offering a more practical and comfortable alternative to the original resin strap. While it may not be the most feature-rich digital hiking watch on the market, it is a perfect companion for casual hikers and outdoor enthusiasts who value simplicity, comfort, and functionality. Personally, I think it is a brilliant move by Casio, and I can't wait to see how it performs in the field.
