Casio is a reputable brand behind many well-known watches, including the F-91W, which I recently purchased. This watch features a sleek black band and blue accents that add character. It offers three modes: Alarm, Stopwatch, and Regular Time. It displays the date and, thanks to its quartz movement, keeps highly accurate time.The battery lasts up to seven years. The watch is splash-resistant. It also includes a light, which does not provide quite enough illumination. but is reasonable for the price. Notably, the F-91W has been worn by figures like former President Barack Obama, the current mayor of New York, Zohran Mamdani, Bill Gates, and Ryan Reynolds. With a price around $20, it’s an easy recommendation for anyone seeking a dependable, sturdy watch.
