SRP453 Automatic Watch

The Seiko SRP453 "2nd Generation Blue Monster, Baby Tuna" is a 46mm men's automatic watch with a stainless steel case and a blue analog dial protected by hardlex crystal. It uses a 4R36 caliber self-winding mechanical movement that can be manually wound and hacked (the second hand stops 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 41 hours when fully wound and will self-wind when moved.
