Rating : - Best Watch Ever?
The Casio F91W1 is perhaps the greatest time piece ever created since Harrison invented the first reliable watch in Greenwich England. It is classy, sleek, reliable and the battery lasts 7 years. While most people strive to constantly score bigger, brighter, clunkier and more expensive watches, I'll stick with the basics - thank you very much.
