Its classic chronograph features a Black/Grey toned dial and a matching stainless-steel case with a three-fold clasp and push-button release. The glass is Curved Sapphire Crystal. This iteration of the Black Series, the Seiko Prospex Black Series ‘Night Speedtimer,’ draws inspiration from night missions and the view through a night scope.
