It was a hard-fought battle for the club, which folded in the late 1950s and was revived in the late 1980s.
It was also a match in which two red cards were handed out, one to Arrowtown and the other to Upper Clutha, and a penalty try was also awarded to the latter, yet the "A-Men" still managed to walk off the field triumphant, with an emphatic 32-17 win.
The cheer from a small, but enthusiastic group of Arrowtown supporters echoed around the ground as the trophy was handed over to the Arrowtown side.
Following the after-match function, the team and some of its supporters went by bus back to Arrowtown and at every stop the trophy was proudly carried by different members of the team - much to the confusion of one boy in Luggate who asked who the "All Black with the trophy" was.
However, there was nothing quite like the roar that echoed through the bus as the team neared its home ground, Jack Reid Park, just after 9pm.
Coach Richie Anderson said the team achieved its goal on Saturday - to win - but the game did not always go exactly as planned.
"That's credit, I suppose, to Upper Clutha.
"With Arrowtown wanting to win and Upper Clutha wanting us to fail to take the championship out, obviously there was a bit of aggravation.
"It's something the referees need to look at and maybe they should have been a bit harder on the people initially," he said.
"I don't want to comment too much on the referee myself, but sometimes what we see is not what he sees."
Despite the red-carding of Hayden Finch, there was little that could take the shine of the team's efforts.
"I'm thrilled for those boys - some of them have never won a championship ever.
"Shane Clearwater, he was a hay bale boy back in 2000 - he used to watch the boys train and now he's a member of the team.
"I'm pretty happy as a coach and so are Daniel Iosefo and Hayden Finch [assistant coaches].
"We've had a good team and we've had a good year.
"Little old Arrowtown, with a population of 1500 or 2000 have just taken out the Central Otago championships."
However, the season was not quite over for the A-Men, with one final battle on the cards this weekend when they go up against South Otago champion Lawrence, at Lawrence, for the Otago Countrywide Championship.
"They should be asking the question `how good are we?'.
"At the end of the day . . . we know where our strengths are and theirs are going to be pretty similar.
"It will be interesting to see who cracks first.
"I don't think it will be us."
There was a question mark over whether Finch, the fullback, would be able to take to the field in the game of the year because he was red-carded near the end of Saturday's match.
Anderson said the coaching staff and Finch would attend a meeting this week to discuss whether he should be allowed to play and put in their "10 cents", fighting for one of the "stalwarts" of the team.
But, yesterday afternoon, the team was still celebrating its win.
"Whatever happens on Saturday, the boys won't forget this," Anderson said.
