The Casio F-91WS-7EF is the white-strap version of the F-91W, the cheap digital watch Casio has sold by the million since the late 1980s. It has a resin case, acrylic glass, a gray LCD, a daily alarm, an hourly time signal, a stopwatch, a countdown timer, a date and day display, a small LED light and a claimed seven-year CR2016 battery. It is tiny and light at about 21 g, so it disappears on the wrist. Rivals like the Casio W-59 and the F-105W add a brighter backlight or a longer strap, but none are as small or as simple. Reviewers treat it as a reliable beater and a design icon rather than a serious timekeeper, and the white resin strap shows dirt faster than the black one.

Owners and reviewers treat the F-91W line as a dependable, almost disposable watch that keeps good time and survives daily abuse. Most praise its size, weight and simplicity; common complaints are the weak light, the scratch-prone acrylic glass and the white strap getting dirty.
This is a Casio watch which is equipped with a gray dial. Among other things, this watch can display today's date.
