Watford's on-loan Udinese pair Almen Abdi and Matej Vydra were both on target in an impressive win over Birmingham City.
Abdi converted from the spot after Steven Caldwell's challenge on Vydra in the penalty area.
Vydra then beat the Birmingham offside trap before sweeping the ball past keeper Jack Butland.
Birmingham offered little threat to the Hornets' goal and are still searching for a league win under boss Lee Clark.
Watford's new-look squad has been bolstered by seven loan signings from Udinese and Grenada - clubs possessed by new Hornets owners the Pozzo family - this summer.
Boss Gianfranco Zola named three of his European recruits in his starting line-up, with Grenada midfielder Daniel Pudil joining Vydra and Abdi in the side, and the trio were involved in both of the goals.
It was Vydra who won the penalty to open the scoring, going down under Caldwell's heavy challenge after Butland had saved smartly from Pudil - Abdi made no mistake with the spot-kick.
And Mark Yeates supplied an accurate through ball for Czech Under-21 international Vydra, who coolly finished to double the lead.
Birmingham kept the ball for long periods in the second half, but only had tame efforts from Nikola Zigic and Marlon King to show for it on a disappointing day for Clark's side.
Watford boss Gianfranco Zola: "I was really pleased with the performance. We scored two goals, created plenty of opportunities and played plenty of good football.
"It is a pity we couldn't keep the same rhythm in the second half and we conceded too much space to Birmingham but that is understandable because Birmingham are a very good team.
"It is something for us to build towards in the future because once our physical condition is better then we will be able to perform like that for longer than 45 minutes."
Birmingham boss Lee Clark: "Watford were excellent and I wouldn't take anything away from their performance but we have given them two very poor goals.
"In general, it was a very poor performance in the first half. We were not good enough in the first half but it is a tough one because I know there is so much more in that dressing room.
"We all have to respond and bounce back and start working out a way to win football matches."
