The Seiko SNK809 (7S26-02J0) is a 37mm men’s automatic watch with a stainless steel case and a black analogue dial protected by hardlex crystal. It uses a 7S26 calibre self-winding mechanical movement that cannot be manually wound or hacked (the secondhand does not stop when the crown is pulled out). It ticks 6 times per second which gives the second hand a smoother movement than quartz watches which tick once per second. The watch should run for up to 43 hours when fully wound and will self-wind when moved.
