like the solar power?, did not keep time once? made me late for a doctors appointment?
2. impossible to change the Day,Date with the chinese directions? the stem must take a micrometer to get the right area to adjust the day/date and it is not as comfortable to wear as the titanium atomic watch it replaced (radio quit after 5 years.
3. not as water resistant or rugged as most watches, sensitive to temperature and I need to take it off to shower. (something my Rolex and titanium did not need)
