The daily alarm reminds you of recurring events by emitting an acoustic signal at the set time. This model features five independent alarms, which are particularly useful for daily medication intake or keeping regular appointments. Once set, the automatic calendar always displays the correct date. The time display can be set in either 12-hour or 24-hour format. In 12-hour mode, a "p" in the display indicates the second half of the day, from 12 noon to 11:59 PM. A battery lasts up to 10 years. Newly developed electronics ensure significantly lower energy consumption. The world time function displays the time in up to 29 different time zones. Perfect for swimming and snorkeling: the watch is waterproof up to 10 bar / 100 meters. The meter measurement refers not to diving depth but to the air pressure applied during the water resistance test. (ISO 22810).
