Club-record signing Isaac Success scored his first goal for Watford as Walter Mazzarri's side came from behind twice to rescue a point against Bournemouth at Vicarage Road.
Callum Wilson gave the Cherries the lead with his second Premier League goal of the season, his near-post header from Junior Stanislas' cross squeezing underneath the body of Heurelho Gomes after 31 minutes.
But Watford improved after the interval and were rewarded when captain Troy Deeney crashed in his third Premier League goal of the season following fine work from Nordin Amrabat.
Joshua King restored Bournemouth's lead within minutes of coming on, but fellow substitute Success met Etienne Capoue's cross to ensure the points were shared.
