The Master Carbon SEAL Automatic with the SELLITA SW 220-1 automatic movement, which also features a day and date window, combines all the details for which Luminox is famous - robustness, luminosity, extreme water resistance, readability. For the first time, Luminox presents an automatic movement in a CARBONOX + case. There is always something very special about a mechanical movement: the way the individual parts interact to bring the movement to life, the balance wheel that rotates and drives the hour and minute hands – it simply brings an indescribable satisfaction to see this reliable and robust automatic movement in motion. The bezel of the Master Carbon SEAL Automatic is made of stainless steel with an IP black plating coating, and the bezel markings are in an absolutely cool steel tone. Of course, the Master Carbon SEAL Automatic is equipped with our Luminox Light Technology, which ensures that the watch is clearly visible even in low or no light and is never dependent on an external light source. Automatic Without batteries and powered exclusively by the arm movements of its wearer, the automatic watch runs permanently. An automatic watch is characterized by its mechanical movement with self-winding. The energy produced by the wearer's arm movement automatically winds the rotor's spring in small steps. When worn daily, the power reserve is sufficient to keep the watch running. However, if the timepiece is not worn for an extended period or not stored in a watch winder, it will stop.
