Stoke brought in Ben Pearson and Sead Haksabanovic to freshen up their side after the 3-1 win at Birmingham in Steven Schumacher's second game as head coach.
Livermore launched an early long-range strike over the Stoke crossbar before defenders blocked replies from Stoke duo Wouter Burger and Andre Vidigal.
Matheus Martins saw a drive deflected wide as Watford came again - and the Hornets took the lead from Chakvetadze's 15th-minute corner.
Ryan Porteous flicked a header across the box for the former England midfielder to bundle over the line. It was his first goal since netting for West Bromwich in an FA Cup game with Chesterfield in January.
Mmaee sent a Stoke chance wide before Yaser Asprilla thumped a drive straight at Potters goalkeeper Jack Bonham.
Mmaee fired Stoke level in the 34th minute after Haksabanovic's run down the left saw the ball bounce off Ryan Porteous to the Morocco striker, who turned to evade Tom Dele-Bashiru before blasting beyond Hornets keeper Ben Hamer.
Junior Tchamadeu missed a great chance for Stoke to take the lead straight after but his shot was too high.
Ismael Kone was booked for a challenge that left McNally requiring treatment. Referee Scott Oldham then showed a yellow card to Ismael for complaining about Stoke challenges that went unpunished.
The half ended with Livermore booked for a late challenge on Haksabanovic - and boos for the referee from the home fans.
Chakvetadze began the second period with a 25-yarder that Bonham touched on to the bar - but Watford were down to 10 men in the 52nd minute when Bayo was shown a red card.
The striker tangled with McNally and, after both players had picked themselves up, appeared to lash out at the Stoke defender with an elbow in full view of the official as play continued.
Hamer came out to make a fine block to stop Bae Jun-ho, played in by Haksabanovic, from slotting Stoke into the lead in the 65th minute.
Watford were still dangerous though, with Bonham denying Asprilla before substitute Mileta Rajovic scooped an even better chance over.
Hamer denied Mmaee a second with a reflex stop, and then had to save low down from substitute Lewis Baker but that turned out to be the game's last clear-cut chance.
The managers
Watford's Valerien Ismael:
"With 10 men we played some great football. The spirit was unbelievable in the stadium - for the first time this season I got some goosebumps. The fans gave us a lot of energy.
"I'm proud of my players because they stayed calm and showed great fighting spirit.
"From minute one we were much better than Tuesday."
Stoke's Steven Schumacher:
"We showed some good character, especially after going 1-0 down from a set-piece. That was a disappointment but we responded really well.
"It was a great finish from Ryan. It was a goal he deserved. He has led the line really well in the last three games.
"At half-time I said to the players that the game was there for the taking if we continued to play with some energy and show more quality in their box.
"Unfortunately, especially when they went to 10 men, we just didn't have that killer pass that would have been the difference.
"It wasn't a poor performance but you could see there were some tired bodies out there."
