Millwall stretched their unbeaten run to eight games with their first away clean sheet of the season in a gutsy goalless draw at Vicarage Road.
It may not have been the prettiest of performances from Kenny Jackett's side, but it was most definitely a spirited one as The Lions finally ended a run of four successive defeats against The Hornets.
A point a piece was probably a fair reflection of the game as neither side was really able to produce that final decisive delivery into the danger zone or killer touch in front of goal.
Watford carved out a couple of half-chances early on with Fernando Forestieri thwarted by a superb tackle from Adam Smith as he broke into the box and then the same player sent a 20-yarder fizzing wide of David Forde's post.
Millwall had an opportunity of their own after 17 minutes when Danny Shittu, returning to his former club, floated a free-kick into the penalty area, the ball fell invitingly to Chris Wood, but his goal-bound shot was blocked by Lloyd Doyley for a corner.
From James Henry's resulting set-piece, defender Mark Beevers sent a looping header over the bar.
A promising Millwall break just before the half hour, started with an excellent tackle by Chris Taylor deep in his own half, ended with another former Vicarage Road favourite Darius Henderson cutting in and sending a curling shot narrowly over.
Henderson was involved again five minutes before the break with a classic piece of route one play by The Lions as Forde launched the ball upfield, Hendo chested on and Liam Trotter hit a low first-time shot a foot wide of the mark.
At the other end Lions defender Beevers was on hand to head off the line when the lively Forestieri latched on to a punched clearance by Forde and fired a shot towards the otherwise empty net.
Millwall had to re-shuffle their playing pack early in the second half when Henry and Henderson were forced off in quick succession with injuries.
Josh Wright and Andy Keogh, both entered the fray but it was Watford who were to ask most of the questions as the game wore on and Troy Deeney twice went close to breaking the deadlock. First, the Hornets striker hit the roof of the net with a drive and he then sent an angled shot agonisingly wide from Jonathan Hogg's cross.
It was pretty much backs to the wall stuff for The Lions as Watford probed and prised the visiting backline, but were unable to break through a resilient rearguard as Jackett's men blocked, cleared and refused to buckle under increasingly intense attacking pressure.
Millwall spent the last quarter of the game playing on the counter-attack, and actually could have nicked all three points right at the death. Keogh's driving run down the right and intelligent pass picked out Wood in space on the left. Although the young striker connected with Keogh's pass on the volley, his powerful shot lacked direction and sailed way over the bar with The Lions last real scoring opportunity of the game.
