Villa were beaten 3-2 by the Hornets, but they never gave up in the fixture.
The Claret and Blues fell behind twice in the contest, but goals from Micah Richards and Jordan Ayew meant they were never totally out of the match, and Garde was pleased with the spirit his team showed.
"The involvement of the players during that game please me," Garde says.
"We made too many mistakes and conceded too many goals to get a result but in terms of commitment and the way we tried to win that game pleased me.
"If you think about the last two games we've conceded seven goals which is huge.
"You have to improve and that's what we're trying to do this week."
It would have been easy for Villa to fold against Watford, given their fragile confidence, but their willingness to fight was admirable.
Villa have not won any of their last 13 Premier League matches, and their desire to put things right was obvious last weekend.
However, individual errors cost them points, and simply fighting hard will not be enough to keep Villa in England’s top flight at this stage.
The Villans are already seven points away from safety, and only a serious up-turn in their results will get them out of trouble, after their disastrous start to the campaign.
