Seiko digital wristwatch, model 0432-5000, is in working condition. Currently operating without any issues. Button responses confirmed. As shown in the second photo, the light turns on when the bottom left button is pushed. Working models of this type are rarely available, so how about it if you're looking for one? It's an old item, so there are scratches. Please consider after viewing the photos. Showa era, antique I am also listing other similar items. Please take a look if you'd like.
