With his first shot in international football, the 25-year-old notched the final goal in a 5-0 win over San Marino.
Watkins had a beaming smile on his face but so too did manager Gareth Southgate and his England teammates, who have clearly welcomed him with open arms after he joined up with the squad at St George's Park.
Post-match, Watkins seemed to be in complete disbelief at what he had just achieved when speaking to ITV and reflecting on his journey.
"It's unbelievable, it's what I've dreamt about to be honest," he said.
"All day in the hotel I was just hoping I would get a chance and get that opportunity to potentially score.
"I didn't know it would happen! I'm speechless to be honest. It's been a good journey. I just feel honoured that I can come out here, put on this shirt and play with the players I'm playing with.
"To score on my debut, I couldn't write it. I'm over the moon to be honest."
Watkins' journey to the top has been anything but ordinary. He was rejected by Exeter as a nine-year-old before returning at Under 11's level and earning a professional contract in 2014.
He then went on loan to non-league Weston-super-Mare in the sixth tier of English football, notching 10 goals in 25 appearances.
Humble as ever, he also helped cleaning the changing rooms before returning to Exeter and forcing his way into the first-team squad under Paul Tisdale.
A move to Brentford followed and he hit double figures in three consecutive seasons in the Championship with the Bees - including 25 in 46 appearances in his final season.

Scoring on your England debut
A brilliant night for Ollie Watkins.
A brilliant advert for developing talent in the EFL.
In the summer, Dean Smith signed him for a second time when he brought him to Villa Park for a fee of £33 million.
Watkins has hit 10 goals in 28 Premier League appearances this term, including a first-half hat-trick in a stunning 7-2 win over Liverpool in October.
His dream debut could put him in contention for the upcoming European Championships in the summer.
He added: "I'm just taking each game as it comes, so focusing on my club form and playing consistently for Aston Villa and help my team to push up the table and hopefully get into Europe.
"We'll see where we go from there."
