In a pre-season of negative results and worrying performances, there was a silver lining for Neil Lennon to consider on Sunday afternoon.
It arrived in the shape of Watt, the Parkhead striker on whose shoulders rest plenty of hope and expectation.
Watt may only be 18-years-old, but he has already started to show why the Hoops were happy to shell out thousands of pounds to sign him from Airdrie, with a brace at Fir Park in the closing weeks of the season undoubtedly his crowning moment to date.
At Firhill on Sunday, he opened his account for the campaign, netting against his former club in the ARR Craib Cup as he turned in a man-of-the-match performance for Stevie Frail's side.
Lennon has already shown his willingness to give the brightest Parkhead proteges the chance to shine at first team level and while Watt remains keen to make the step-up once again, he knows the Firhill outing is only the start of the hard work that will be needed.
"It is too early," Watt said. "I have had one good game, I won't get ahead of myself. Hopefully I can go and train with them over the next week or two and then we will see what happens.
"People like Gary Hooper and Anthony Stokes are obviously doing well for the first team so you have got to look at what they are doing and what you could do to make yourself as good a player as them. Georgios Samaras is very direct and goes at people, so hopefully I can do that, too.
"I don't expect to play regularly for the first team, but if I can then that is a bonus obviously. Hopefully I can do well and impress the manager and maybe get on the bench a few times. I just need to see what happens and keep working away."
Watt may have stolen the show as an inexperienced Hoops side saw off Jimmy Boyle's Irn-Bru First Division outfit, with Patrik Twardzik, Callum McGregor and Glen Eadie also on target, but it was no easy weekend for Frail's stars.
The Lennoxtown boss was left furious with his side following their 2-0 defeat to hosts Partick Thistle on Saturday and Watt admits the criticism hit home as they made amends during their second fixture.
He said: "I had a bad game on Saturday, I wanted to make up for it. I wasn't at my best so I wanted to go and make a point and prove to people. You can't be a passenger when the team is doing well. I wanted to go and do well and impress.
"People around us weren't happy and people had to try and redeem themselves. We did that, we all did well."
A below-par showing against the Jags meant that it would be Airdrie, and not an Everton XI lead by former Hoops hero Alan Stubbs, that Celtic would face during Sunday's action.
It gave Watt the chance to test himself against some familiar faces, however, with the teenager proving a menace to his former club as he set up Twardzik for the opener before grabbing a goal himself, an act he could, and should, have repeated on more than one occasion.
It was a far more contented Frail who hailed Watt's contribution in the aftermath of a comfortable win for the Parkhead youngsters and the striker was keen to please mentors past and present.
Watt said: "It [my low key celebration] was out of respect to Jimmy. He has done a lot for me. I still keep in touch with him, he has been brilliant with me.
"When I do good he tells me and when I do bad he tells me what I have done wrong. He still comes to our games, too. He was the assistant manager when I went in on trial and he told them to sign me.
"He gave me a few shots at 19s and gave me my first profes- sional contract and debut. I was only on the bench three times and I started about 15 games so he has done a lot for me."
While Watt's long-term future in the game appears bright, his immediate plans are subject to change.
A sustained period of first team action would cap a dream few months for the striker, but it is in Celtic's Development Squad where he is likely to turn out on a more frequent basis as the Hoops attempt to progress their most promising talents with matches against English opposition rather than in Scotland's youth set-up.
"The standard in the Development Squad games is higher than that in the 19s or 20s," he said.
"When you are playing against better players, you are going to play better and try harder. If you are playing against better players then you are testing yourself. You come up against players that are coming back from injury and that aren't getting a game, too."
