Talk:Electronic Castlevania II: Simon's Quest

Confused about the release dates.
The info box of the handheld game says that the release date of that game was on December 31, 1988. The info box for the LCD watch version says that that version was released in 1989.

Yet, on the section Differences from the LCD Watch Version, it says that the LCD watch was released before the handheld. Which one is right?
