Emmanuel Dennis' late header gave Roy Hodgson his first goal and first win as Watford boss, and earned the Hornets a valuable win at Aston Villa.
Villa dominated proceedings but Watford grabbed all three points when Dennis powered home Ismaila Sarr's 78th-minute cross after an opportunistic counter-attack.
It ended the visitors' four-game goal drought and saw them move up to 18th in the table, four points off safety.
Defeat for Villa means Steven Gerrard's side are now winless in seven of their past eight matches.
