Burnley claimed a second victory of the season and ended Watford’s winning run with an assured display at Turf Moor.
The home side dominated the first half and their first-half pressure paid off when Jeff Hendrick headed in Steven Defour’s corner.
Watford looked to level matters after the break, but within five minutes of the restart were two down.
A minute after Tom Heaton had saved Troy Deeney’s shot, at the other end Michael Keane nodded in Defour’s cross.
The closest Watford came to a goal was when Isaac Success ran down the left on 83 minutes and his shot from a narrow angle was tipped just wide.
The result means Burnley rose to 13th while Watford dropped to 11th.
