Other Casio models in the same style as this model was criticized for too short a bracelet, so I hesitated before buying as the descriptive information is vague. But no problem, the total length is 24 cm including 21 useful, unless you Dockers arm should be for all adults. As against the sensitivity of the buttons is too large and I found frequently (at least once a day) display 12h instead of 24 or you name it chrono mode; This is not fatal but very annoying. My old Casio watch, which unfortunately I no longer find suitable bracelet, did not have this defect.
