SARN003 Automatic Watch

The Seiko GMT Retrograde SARN003 is a 40mm men's automatic watch with a stainless steel case and a blue analog dial protected by sapphire crystal. It uses a 4S36 caliber self-winding mechanical movement that can be manually wound and hacked (the second hand stops when the crown is pulled out). It ticks 8 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 50 hours when fully wound and will self-wind when moved.
