The Owls posted another valuable Championship point, playing out a goalless draw with Watford at Hillsborough.
Sustained first half dominance might have spawned all three on another day but a convincing all-round display supplemented by a fourth successive clean sheet led the positives.
Only a goal was missing from the opening 45 and although the Hornets gave a better account of themselves after the break, few would deny that Wednesday deserved the win.
It was all the hosts from the off as Watford were pinned in their own half and under increasing pressure.
Izzy Brown pulled the strings with Barry Bannan in the engine room, while Josh Windass sent a couple of sighters the way of Ben Foster between the sticks.
The visitors, though, were dangerous given their Premier League credentials of last season, as was evidenced when Glenn Murray stung the hands of Cameron Dawson from range.
The ball was promptly back at the other end, where Brown picked out Dominic Iorfa with an accurate set piece but the defender’s header was wayward.
Watford then survived a penalty appeal after Windass tangled with Christian Kabasele with half time approaching before Tom Lees glanced another Brown free kick wide almost on the whistle.
The second half was a scrappier affair as neither side could truly take a grip. But it was Watford that threatened the breakthrough first when substitute Stipe Perica forced a fine Dawson save from his first involvement.
The Hornets had the upper hand as the contest unfolded and Dawson again came to the rescue.
Tom Cleverley advanced into the penalty area on the angle and his show was hard and low but Dawson sprung athletically to palm clear.
A concession would have been hard on the hosts, though, and indeed they hit back to have the final word as Brown glanced a Liam Palmer cross wide.
Wednesday: Dawson, Harris, Iorfa, Lees, van Aken, Penney (Palmer 55), Bannan, Brown, Luongo, Rhodes (Kachunga 69), Windass (Reach 86)
