The dial indicates "CALIBRE 5 AUTOMATIC," which means it is powered by an automatic (self-winding) mechanical movement. The Calibre 5 is based on a Swiss-made ETA or Sellita base movement, known for its reliability.
Design: It features a black dial with a horizontal striped pattern and a black unidirectional rotating dive bezel. The hour markers and hands are luminous for visibility in low-light conditions. A date window is positioned at 3 o'clock with a cyclops magnifier on the sapphire crystal.
Case and Bracelet: The watch has a stainless steel case and a matching stainless steel bracelet, which appears to have a mix of brushed and polished finishes
