Daily recurring events are reminded by the daily alarm, which sounds an acoustic signal at the set time. This model has five independent alarms - especially convenient for taking medication daily or keeping regular appointments. For about 5 years, the battery provides the watch with the necessary energy. At the push of a button, the dial or display of the watch is illuminated particularly brightly and in color, so that you can see everything even in total darkness. Once set, the automatic calendar always shows the correct date. The time display can be set to either 12-hour or 24-hour format. If desired, the key tones can be switched off with the mode button. After switching off, there is then no longer a beep when changing from one function to the next. Set alarms or countdown timers are still active after the key tones are turned off. At the push of a button, the hands release the view of the digital displays, so that e.g. stop function or day of the week can be read without restriction. For athletes and all those who want to know exactly: Elapsed time, split time and final time are measured with an accuracy of hundredths of a second. The measuring capacity of the watch lasts up to 24 hours. The countdown timer helps to remember special or recurring events by emitting an acoustic signal at the set time. The time can be set every minute and up to 1 hour in advance. After you stop the alarm signal, it will automatically sound again after a few minutes. The world time function displays the times in up to 29 different time zones.
