SEIKO SEIKO SOLAR Pair Watch with Date Display

Found during a decluttering of my parents' home, this pair of Seiko watches features a date display. When exposed to fluorescent and sunlight, both the larger and smaller watches started working. After observing them for several days, I found that they stop within a short time when stored in darkness.
It is assumed that the rechargeable battery for light charging has deteriorated. Therefore, this item is being listed as a junk item.
