The surface of the watch glass is curved, providing high stability and resistance to pressure. Resin is made from synthetic resin and, due to its extreme durability and flexibility, is the ideal material for straps. The watch requires a battery change every 10 years. Newly developed electronics ensure significantly lower energy consumption. Showering and bathing are possible with this watch, as it has been tested for water resistance up to 5 bar according to ISO 22810. To keep everything in view even in dark environments, the watch display is illuminated by a light-emitting diode at the push of a button. A second time zone can be set and accessed, which is ideal for frequent overseas calls. The daily alarm reminds you of recurring events with 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.
