The Seiko Men"s 5 Automatic Blue Dial Stainless Steel Watch boasts high-tech Japanese automatic movement hidden behind classic analog styling. Precise 21-jewel Japanese automatic movement keeps this watch functioning without a battery: It is powered automatically with the movement of your arm. This high-tech feature is tucked away behind the watch"s blue dial, which boasts luminous silver-toned hands and baton hour markers. The dial also sports a date window at the three o"clock position, and the entire dial is protected by a mineral crystal. Keeping all of this securely on your wrist is a polished stainless steel link bracelet that closes with a fold-over double push-button safety clasp. Other features include a stainless steel case and water-resistance to 99 feet (30 meters).
