Nelsonic Game Watch

The Nelsonic Game Watch is a multi-purpose wristwatch developed by that uses an LCD display. Nelsonic obtained licensing from Nintendo in 1989 to adapt many of Nintendo's popular games, including various Mario entries; these were done in a much simpler Game & Watch style format, due to the game watch's limitations. The instruction leaflets contain many capitalization mistakes as well as poor grammar and spelling. All of the Nelsonic Game Watch products were released in North America, and were produced while Nelsonic acted as a division of the watch-making company M. Z. Berger prior to and after their acquisition in 1990.

This is a list of Mario games that were made for the Nelsonic Game Watch:
 * Super Mario Bros. (based on Super Mario Bros.) (1989)
 * Super Mario Bros. 3 (based on Super Mario Bros. 3) (1990)
 * Super Mario World (based on Super Mario World) (1991)
 * Donkey Kong (based on Stage 1-7 of the Game Boy version of Donkey Kong) (1994)

The latter three were released as tie-in products with Nintendo's games. Donkey Kong was also available through a discounted mail-in offer with Kellogg's Corn Flakes breakfast cereal. However, the cereal box shows a possible unreleased prototype as it depicts 25m. The Super Mario Bros. 3 watch was re-released in Europe, along with a couple of other Nelsonic Game Watches, by UK-based timepiece distributor Zeon in late 1992. Zeon also distributed the Super Mario World and Donkey Kong watches.
