Casio F-91WF Review: The Ultimate Hiking Watch Upgrade You Never Knew You Needed! (2026)

Casio's iconic F-91W watch, a timeless classic since 1989, has received a trail-ready makeover. The F-91WF, a fabric-strap variant, is a game-changer for hikers seeking a lightweight, comfortable, and low-maintenance companion. While the core specifications remain unchanged, the introduction of woven fabric as a strap material is a subtle yet significant innovation.

The F-91W's enduring appeal lies in its simplicity and practicality. Housed in a lightweight resin case, it offers basic water resistance and essential features, all at an affordable price point. However, the original resin strap has been a point of contention for outdoor enthusiasts, often causing discomfort during long hikes. Casio's solution? A simple yet effective swap to woven fabric.

This change is more than just a material swap; it's a recognition of the F-91W's versatility and its potential as a hiking watch. The fabric strap breathes better, reducing sweat buildup, and its texture provides a more natural feel on the wrist. This upgrade is a testament to Casio's understanding of its customer base and their specific needs.

The F-91WF retains the core features of its predecessor, including the digital module, resin case, and compact proportions. It's available in three colors: black, navy, and olive green, and measures 35.2mm wide and 8.5mm thick, with 30m water resistance. The watch operates on a single CR2016 battery, ensuring seven years of reliable performance with stopwatch, daily alarm, and auto-calendar functions.

While the F-91W is not a serious digital hiking watch, its charm and practicality keep it in high demand. It offers a lightweight, comfortable, and low-maintenance option, even at a price point that's twice that of the standard model. The F-91WF's price in Thailand is around $48, and while US pricing is yet to be confirmed, it's expected to be slightly higher.

Casio's attention to detail and willingness to adapt to customer needs is commendable. The F-91WF is a testament to their commitment to innovation while preserving the essence of their iconic timepieces. As an associate editor at Gear Patrol, Ethan Brehm highlights the F-91WF's potential, emphasizing its appeal to hikers and outdoor enthusiasts.
