The watch CASIO F201WA matches my expectations. Points Positives: - Quite small, light. - Cool features. Negative points: - Lack of precision. Tend to move forward. Approx. 2-3 min / month - The functionality to switch between 12h / 24h display is accessed directly on one of the buttons and changes unintentionally.
For the duration of the battery it will take 10 years if I believe the data sheet! Overall: good buy and correct price
