Howe cited the performance of Hornets stopper Heurelho Gomes as one of the main reasons why his side weren't able to pick up the victory, as the Brazilian made superb saves to deny both Harry Arter and Max Gradel in the second-half.
"Any point away from home is a good point," Howe said.
"But we're disappointed on reflection, I felt we were the dominant side and their goalkeeper had another great game against us.
"In the two games last season he was excellent too.
"Today, I thought the strike from Harry Arter was in from my angle, but he got a big hand on it. The save from Max Gradel's header was also a big one.
"The pleasing thing from our perspective is we created those chances in the second-half after not threatening much in the first.
"I'd bank on us the next time we get those chances to be more clinical with them."
After an early injury to Junior Stanislas, Max Gradel made his return from injury and put in a lively shift at Vicarage Road.
Howe was pleased to welcome the Ivorian back into the side.
"I thought he was a key part in our performance today," Howe continued.
"It was a really good appearance and he was unlucky not to get a goal, he's a player that makes things happen and we were pleased to welcome him back.
"Him being back round the squad has given everyone a lift."
