The 29-year-old spent a month with the Hornets at the back-end of 2014 and now moves to Vicarage Road on a three-month deal until the end of the season.
He isn't available to feature this afternoon against Leeds United, but could play against Fulham on Tuesday night.
In his stint earlier this term, the Algerian international scored twice in six appearances.
