The watch arrived earlier than anticipated. I'd downloaded the watch manual from Casio which turned out to be a good thing as the wee instruction book would have been difficult for me to read. I was quickly able to set the time on the watch. Fairly straight forward. I am delighted with the size and weight. Unlike a Stauer watch it fits comfortably and snugly on my wrist. The Stauer watch was supposed to be perpetual, but died 3 months after the warrantee expired. It was heavy and clunky and now resides in a drawer with other dead watches. If this watch lasts 2 years, it will have been a good investment. I do have some reservations as how well the strap will wear over the years, but again the price was right.
