This is an automatic mechanical men's watch from the Seiko 5 Sports series. It uses the 4R36 movement, which winds itself and can also be wound by hand. The movement has 24 jewels and a power reserve of about 41 hours when fully wound.
The case is stainless steel with a curved hardened glass crystal. A screw-down see-through case back, made of stainless steel and glass, shows the movement. The hands and markers have a luminescent coating. The watch is water resistant to 10 ATM and is magnetic resistant. It closes with a single push-button triple-fold clasp.
