I like this watch but as I have begun using it more at night a problem has arisen. The luminosity is good but the fact that the hour and minute hands are only luminescent as dots causes a problem where sometimes the the minute hand blends into the markers and gets lost especially at a glance. It also is ocassionally hard to tell the minute hand quickly from the hour hand. This all could have been fixed easily if Seiko had coated the entire hands with the luminous material. I viewed the pictures of the night time illumination on line and the pictures looked much clearer than it does in real life. It appears well built. It is an attractive watch and the kinetic feature keeps it charged wearing it only part of the day.
