Compare Seiko Kinetic Titanium Watch to Seiko SKH640 Wrist Watch for Men

Unlike any other watch. This style is powered by your movement - the first quartz watch of its kind - so it never needs a battery or winding! Here's how it works. An oscillating weight is rotated by the movement of your wrist. This movement is transformed into a magnetic charge, then into electricity, which is stored in a tiny capacitor or a rechargeable battery. And a power reserve indicator shows exactly how much energy you?ve created. The rest of the watch is excellent, too. Featuring a charcoal dial of hands and indexes that light up for easy nighttime visibility. With a date display. And precise quartz movement for reliability. Easy-wearing bracelet. Made of titanium. In silver/gold. Time out! Take a minute to check our Product Guide for timeless watch information! Water-resistant to 100 meters Stainless steel back Battery operated Less
