To ensure visibility in dark environments, the background lighting illuminates at the push of a button. Elapsed time, split time, and final time are measured with an accuracy of hundredths of a second. The watch has a measuring capacity of 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. In 12-hour mode, a "p" in the display indicates the second half of the day, from 12 noon to 11:59 PM. Hard, durable, and elegant: the stainless steel bracelet is a classic for watches. For optimal wearing comfort, the clasp can be easily and individually adjusted. The battery powers the watch for approximately 7 years. This model is waterproof according to DIN 8310 and ISO 22810, meaning it can withstand light splashes. Greater water contact should be avoided.
