The 30-year-old, who will miss the next two games after being sanctioned for a high hit on Collingwood's Jamie Elliott, will have to fight his way back into the team if he's to rack up the three games he needs to reach 200.
"I haven't even though about milestones, and I understand that will become more of a discussion as the year progresses," Watters said on Wednesday.
"But the focuses are pretty simple for ‘Kosi’ – get yourself fit, get yourself in good form and fight your way back into the team.
"They're the issues he needs to address.
"Do your penance, go back, play well, put your hand up for selection. That's the simple formula.
"This week he's suspended, next week he's suspended, we look at his form and where the side is at."
Watters said it was disappointing when any player was suspended, but believed Koschitzke had explained his actions well.
"They were clumsy by his own admission, he's apologised, he's remorseful," he said.
"You're disappointed when any player gets suspended because you want your quality players and your leaders out there.
"He's a quality individual, ‘Kosi’, so being suspended hits him pretty hard, but he has to grow and work through that."
Meanwhile, Koschitzke has hit back at critics who have suggested his career is over and says he still has plenty to offer.
Former Essendon captain Matthew Lloyd suggested on Channel Nine on Sunday he might not play at senior level again in the wake of the suspension.
But Koschitzke, who has since apologised to Elliott, says he's determined to finish off the season strongly.
"I'm by no means done, as a lot of people out there are jumping to some conclusions and saying," Koschitzke told the club's website.
"The body feels good. I've been around a while now and if I'm not contributing on the ground … it has been a really good learning experience being able to play in the VFL and almost coach some of the kids in the pressures and physical demands of playing AFL footy.
"I've still got the year to go, we're still very young in the year and other people are going to get their chance.
"I'll be working pretty hard to get back out there and put the red, white and black on again and finish the year off on a positive note."
Koschitzke said he had done the wrong thing and wanted his remorse known.
"I don't want to be recognised or remembered as someone that's going to do those things off the play," he said.
"It's not what we’re about as a club and certainly not what I’m about.
"It was accidental. I was just trying to check Jamie off the ball and obviously clumsiness made it look a bit dirtier than what the intention was about."
The veteran big man said Elliott accepted his apology when he called to check on his welfare.
"I think he was quite surprised I called him. He just said, 'No worries'. He knew I didn't mean anything dirty by it and that I was just checking him off the ball and blocking his run," he said.
"He knew I didn't mean to get him high, so it was good to put that at ease."
Koschitzke said he was now determined to turn his forced hiatus into a positive by helping whoever replaced him in the team.
"I've got two weeks to go and train and let my actions do the talking and really help the young kids," he said.
"I've left a hole again in the side, so somebody will get the chance to play up forward. I'll just work closely with whoever that is and make sure they're going well and learning from the experience.
"That's got to be my role in the next few weeks – to make sure the club goes forward and get myself in the best position to be selected again after the suspension's finished."
