Query: Great watch to have.

I bought this watch last week, and it sure is a great one for work or play or even dress! The time calibration works very well here in Kalamazoo, MI. I did a manual time calibration when I first got it and it worked right away. It even does it automaticly at night during the time I'm asleep and I have it on my wrist all night. The solar charg/power feature is great too. No need to worry about changing a battery every year. According to instructions you "may" have to at one point in time, but several years down the road. That's no big deal to me. The numbers are easy to see with my visual impairment. I'm glad I purchased this watch and reccomend it highly. I'd give it 10 stars if that was possible. I've had good luck with "Casio" in the past and will probably purchase from them again if necessary.
