It is rare for a consumer electronics product to remain culturally and commercially relevant for decades, but the Casio F-91W has achieved exactly that. Since its debut, the unassuming digital watch has become a global constant, recognized for its minimalist design, practical functionality, and an accessible price point—currently hovering around $22 for a new unit. Its lightweight resin case, paired with a straightforward stopwatch, daily alarm, and signature backlight, has cemented its status as a permanent pillar in the Casio catalog.
An Eco-Conscious Material Shift
Signs now point to a fresh evolution of the classic. A product listing from G-Shock Hai Phong has surfaced for a new model, the F-91WF, which preserves the familiar digital face of its predecessor while introducing a notable material change. The standard resin strap is replaced by one crafted from recycled fiber. Casio describes the textile-like band as lightweight and engineered for extended comfort, adding that it is also designed to resist scratches and the accumulation of dirt.
Subtle Upgrades Under the Hood
The core specifications remain faithful to the original formula, with a few incremental refinements. The module maintains a day-and-date display, a daily alarm, and a stopwatch, though the latter now gains 1/100-second precision along with elapsed time, split time, and finish-order timing modes. As with the classic version, February is hard-coded at 28 days, requiring a manual correction for leap years. Accuracy is rated at ±30 seconds per month, and a CR2016 battery is projected to last roughly seven years. Physically, the watch remains nearly identical in proportion, measuring 38.2 x 35.2 x 8.5 mm and weighing a mere 21 grams.
A Familiar Silhouette in New Tones
Three initial colorways have been revealed so far: black, navy, and olive green. While an August launch window appears likely based on the listing, Casio has yet to issue an official statement confirming pricing or a definitive release date. As with any pre-release information, the details should be viewed with some caution until the company makes a formal announcement.
