Both teams improved after half-time but neither could make the breakthrough at Vicarage Road, with the Nigerian missing an easy-looking second-half chance with his head
Watford and Bournemouth both had their fair share of chances but neither could produce a goal as they drew 0-0 at Vicarage Road in the Premier League.
Odion Ighalo came close to scoring an early opener only for Adam Federici to make a good save as the Hornets started well but could not find the goal that their dominance deserved.
Bournemouth were on top after the interval and a fine Heurelho Gomes save kept out Harry Arter's left-footed drive from fully 25 yards.
Valon Behrami could have conceded a penalty for a handball before Ighalo missed the match's clearest chance by heading over a Nordin Amrabat cross.
It was the 100th league meeting between the sides and both clubs remain tied on 35 victories apiece after this stalemate.
Quique Sanchez Flores recalled top scorer Ighalo, who was rested for last weekend's 1-0 FA Cup win against Leeds United, while Bournemouth welcomed back Max Gradel to their squad after six months out with a knee injury.
Ighalo almost gave Watford a flying start inside two minutes when he burst clear of Arter and Steve Cook but Federici made a good save. The 14-goal striker then screwed a shot wide from eight yards after Amrabat played in Juan Carlos Paredes down the right wing as Watford started the match well on top.
Arter shot off target for Bournemouth after 12 minutes, with Amrabat's effort deflecting wide off Cook moments later.
Gradel then made an early substitute appearance on his comeback due to Junior Stanislas pulling up with a hamstring injury but the game remained one of few chances.
The first opening of the second half fell to Josh King after 52 minutes but the striker turned a fine Matt Ritchie cross over the crossbar.
Bournemouth, who have now only lost one of their last eight away league games, then put together the best move of the game to free Gradel, who shot over under pressure from Miguel Britos.
Gomes preserved Watford's second clean sheet in 10 matches on the hour-mark, diving to his left to superbly keep out a 25-yard Arter drive, before Behrami was fortunate not to concede a penalty for handling a cross.
After 66 minutes Ighalo missed the best chance of the game, heading Amrabat's delivery over the crossbar.
Ighalo missed the target again after 75 minutes, turning inside and shooting over from a good position after Ben Watson took a quick free-kick.
Substitute Dan Gosling could only turn a loose ball into Gomes's arms before the goalkeeper saved a header by Gradel.
Despite a frantic finale the game remained goalless, meaning that Watford missed a chance to climb to eighth in the Premier League, while the point edges Bournemouth away from the relegation zone.
