The item is a Seiko automatic divers watch that is water proof up to 200 meters or 660 feet deep. The case back is threaded. The watch has a one way rotating bezel and the hands and markers will glow in the dark. There is a date at the 3 position on the dial. The case is 44 millimeters wide and the band width is 22 millimeters wide. This watch will come with a three year warranty and I will include all the paper work along with the box.
