Casio F-91WS-2EF

Elapsed time, interval time, and end time are measured with an accuracy of hundredths of a second. The watch's measurement capacity extends up to one hour. The daily alarm reminds you of recurring events, sounding an acoustic signal at the set time. Once set, the automatic calendar always displays the correct date. The time display can be optionally set to a 12- or 24-hour format.
