SNK578 Automatic Watch

The Seiko SNK578 is a 37mm men's automatic watch with a stainless steel case and a green-yellow analog dial protected by hardlex crystal. It uses a 7S26 caliber self-winding mechanical movement that cannot be manually wound or hacked (the second hand does not stop when the crown is pulled out). It ticks 6 times per second which gives the second hand a smoother movement than a quartz watch which ticks once per second. The watch should run for up to 43 hours when fully wound and will self-wind when moved.
