A light-emitting diode (LED) is used to illuminate the watch face. Shock-resistant construction protects against impact and vibration. Displays the current time in major cities and specific areas around the world. Elapsed time, split time and final time are measured with 1/100-sec accuracy. The watch can measure times of up to 24 hours. For fans of precision: the countdown timers help you to remember specific or recurring events by giving off an audible signal at a preset time. The time can be set to the nearest minute and up to 24 hours in advance. Ideal for people who need to take medicines every day or those who do interval training. The daily alarm reminds you about recurring events with an acoustic signal at the time you have set. This model has 5 independent alarms for flexible reminders of important appointments. With a push of a button, hands are moving and permit a free visibility of functions like stopwatch or date. Once set, the automatic calendar always displays the correct date. Times can be displayed in either a 12-hour or 24-hour format. The tough mineral glass resists scratching. Thanks to its extremely high level of durability, resin is the ideal material for watches. Combining resin with carbon—a particularly robust material—creates a casing that is even more stress-resistant and offers even greater protection against external influences, resulting in an extremely high level of durability.
