SYMK39

The Seiko SYMK39 is a 23mm women's automatic watch with a stainless steel case and a silver analog dial protected by hardlex crystal. It uses a 4207 caliber self-winding mechanical movement that can be manually wound but cannot be 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 24 hours when fully wound and will self-wind when moved.
