Watches made for TV series, characters, or films come in all manner of different styles and qualities.
This is a watch for the character Mighty Atom (or Tetsuwan Atomu) who is better known in the West as Astro Boy. This is the third Astro Boy watch, but is at the other end of the scale from the previous watches which were a Seiko AirPro and an GSX limited edition. The Astro Boy /Mighty Atom story is about a scientist who builds a robot boy as a replacement by a Dr Tenma for his son who was killed in an accident. When he realised the robot could never be human, he was given to a circus but rescued by a Prof Ochanomizu and ended up using his power to help fight crime, injustice, and other threats to humanity. The cartoon was created in a Japanese manga in1952 by Osamu Tezuka, who is known as the God of Manga.
This watch is a simple LCD watch for Mighty Atom with a 4 digit LCD, and the usual time, date, and seconds displays. It is a little temperamental so I couldn't get the display to stay on for the post. Around the LCD window is a hologram style sticker with a picture of Mighty Atom, his name, and the copyright to Tezuka Productions.
To get to the insides, you need to take off to tabs from the top and bottom of the case, and then the glass can be removed and the module lifted out. There is no way in from the back which is solid plastic, and only reveals this was made in China.
I'd guess that this was an 80s watch from the styling of the graphics, but is could a a cheap later model instead.
As an extra bonus - The background that the watch is sat on in the pictures is an original drawing used in some of the frames of the Anime.
