I've got a different model in that line:
Solar-powered, radio-controlled and accurate to the second. No time to set, no batteries to change. The only thing you ever set is the timezone when traveling — the hands wind forward or backward to the new local time in a couple of seconds. The daylight saving switch is automatic. Had it six years. Cost $130, if memory serves, but available for considerably less without the titanium band. Casio markets essentially the same watch under the Oceanus brand for five or six times that price. The Japanese have forgotten more about horology than the Swiss know.
I tend to forget to wear it a lot of late, however. It's redundant when also carrying a phone.
