The watch is equipped with energy-saving Bluetooth technology that offers power-efficient data exchange at the push of a button. Via Bluetooth, the watch can connect wirelessly to a smartphone, allowing access to a variety of useful features. Once the watch is paired with the smartphone, the time is automatically set, displaying the current local time worldwide. Independent and environmentally friendly, solar cells provide the watch's power supply. Excess solar energy is stored in a battery. The hands and index are coated with a fluorescent material, glowing in the dark after being exposed to a light source. With the dual time display, you always have a second time zone in view. The stopwatch function measures elapsed time, split time, and final time with an accuracy of one-thousandth of a second. The watch can measure for up to 24 hours. This memory can store measured lap, split, and final times along with the date, which can be displayed later. A record consists of the date, stopwatch, lap, and split times. The memory can hold up to 200 such records. Misplaced your smartphone? A single press of a button on the watch is enough, and the smartphone will emit an alarm.
