City wrapped up the season at St Mary's with a late 1-0 win over Southampton thanks to striker Gabriel Jesus' delicate lob in stoppage time to spark wild scenes on the sidelines.
Guardiola feels his team have been rewarded for their playing style and doubts their record exploits will be matched anytime soon.
"It's incredible. I don't have the words, 50 points at home, 50 points away. Incredible, incredible," he said after the game, as quoted by BBC Football.
"When you get to 100 points, it's something special for all the club. It's a record which will stay for long."
Despite breaking the records for points, goals scored and wins on their way to the title this season, the Spaniard insists it's not what pleased him the most about his first Premier League crown.
"Numbers are numbers, but I think the way we played. We didn't play 38 games perfectly, but most of them we were so good, and most of the time we were better than our opponents.
"Every game you have to try and be better than your opponent - that's the only thing. When you score a lot of goals and concede few, 100 points, all the records we have broken, it was a consequence of the way we've played."
