This is a new Seiko automatic 5 Sports watch that features a Seiko 24 jewel automatic (self-winding, hand wind, hacks) movement. The transparent dial is reminiscent of the original "Time Sonar" watch from the 1970's. Beneath the brown tinted dial you can see the day and date wheels, very cool! The brown dial has a day and date display at 3:00, highly luminous hands and markers treated with Lumibrite for low light visibility, an offset crown at 4:00, a uni-directional rotating bezel, a Hardlex mineral crystal and an exhibition window screw-down case back. 42.5mm diameter stainless steel case. It comes on a stainless steel bracelet with a deployant clasp
