For Luton's manager, Lenny Lawrence, the biggest pleasure was seeing his team matching Watford's pace and fitness only two days after being humiliated 6-2 in the FA Cup at Bolton.
"We defended well and had three or four half chances," he said. "But Watford always got men behind the ball."
The draw keeps Luton in second place in the Second Division and the Watford manager, Kenny Jackett, confessed it was frustrating for him to see his side becoming draw specialists. They have extended their unbeaten run to a club record of 21 league and cup games without defeat, but that includes 13 draws, leaving them in mid-table.
But he was grateful for the point at Luton as he had five first-teamers out through injury and, during the game, lost another -the striker David Connolly with a hamstring injury.
He said: "It can get frustrating to get so many draws but if we beat Rotherham on Saturday this one at Luton will be a very good point."
Watford defended in numbers and 18-year-old Darren Ward had an impressive debut at centre-back.
The nearest Luton got to breaking the deadlock was when defender Steve Davis went upfield for a 56th minute corner and shot against a post.
Watford threatened in the closing minutes and substitute Wayne Andrews forced a save out of Ian Feuer with their first on-target shot after 77 minutes.Reuse content
