CASIO Casual Watch F-91WS-4EF – A Classic Digital Timepiece for Women

The CASIO F‑91WS‑4EF is a timeless example of Casio’s commitment to reliable, stylish digital watches. Designed in the 2020 Spring/Summer collection, this model blends classic aesthetics with modern functionality, making it an ideal choice for everyday wear.

Design & Build Quality

The watch features a pink case that gives it a fresh, feminine look while maintaining the iconic Casio silhouette. The rectangular case measures 38.2 mm × 33.20 mm × 8.5 mm, with a diameter of 33 mm, striking a balance between presence and comfort on the wrist.

The case is constructed from durable plastic (resin), ensuring lightweight wear without compromising sturdiness. The front crystal is made of Plexi glass, offering scratch resistance and clarity for the digital display.

Display & Functionality

At its core, the F‑91WS‑4EF offers a clear digital time display that shows hours in an easy-to-read format. The watch’s primary function is to keep accurate time, but it also includes several useful features:

  • Hourly Time Signal Alarm: Provides a gentle notification every hour.
  • Stopwatch / Chronograph: Measures elapsed time with a precision of 1/100 seconds, up to one hour.
  • Timer Function: Allows you to set countdowns for various activities.
  • Daily Alarm: Set a daily reminder at a chosen time.
  • Automatic Calendar: Keeps track of the date without manual adjustment.

Strap & Comfort

The watch comes with an original resin strap (Casio 10605129 Collection Women), which is both lightweight and flexible. The strap’s pink hue complements the case, creating a cohesive look that can be worn for casual or semi-formal occasions.

Power & Durability

The F‑91WS‑4EF runs on a CR2016 quartz battery, known for its long life. With an expected lifespan of 84 months (7 years), the watch offers reliable performance with minimal maintenance.

While the watch is not water-resistant (0 bar), it can handle light exposure to moisture, making it suitable for everyday use without submerging in water.
