Casio Edifice Chronograph EF-552D-1AV EF-552D-1A Mens WatchCasio Edifice Chronograph EF 552D 1AV EF 552D 1A Mens Watch Calling it beautiful or sporty will only give you a vague idea about the watch; its real beauty is in its durability, precision and the crank case design encircling the seconds and 24 hr hand. The hands fall in exactly where the marks are; the kind of accuracy usually found in more expensive ones and runs on shoestring power, which will keep the factory seal intact longer than many others.
