Gamewatch Boy

The Gamewatch Boy (or GameWatch Boy) is a wristwatch developed by Mani Industries (万信) of Hong Kong. It resembles a miniature Game Boy and has an LCD display that can play games. While it comes in a variety of colors, only two games were ever developed, and both are Mario games: Dr. Mario and Super Mario Race. Both games have an A (beginner) and B (expert) difficulty setting. They were first released in 1992, and production continued until at least 1995. Like the Nelsonic Game Watch, they were distributed in Europe by Zeon.
