Eight questions into his pre-tournament press conference on Tuesday, the emotional left-hander was asked about the most interesting thing he had done with the Green Jacket since he won it 12 months ago, and that was all it took.
Wiping away tears, Watson explained: "Out of respect and honour for Augusta National, as one of greatest clubs we have, as one of the greatest tournaments, out of respect for them, I didn't do any of my funny antics that I normally would do.
"Only thing I did was wrap Caleb up in it."
Caleb is the son he and wife Angie had adopted shortly before last year's Masters, who will be here this year to see if his father can become the first player since Tiger Woods in 2002 to successfully defend the title.
"Obviously my stats probably show that I was better last year," added Watson, whose best finish of fourth this season came back in January.
"My mind, my physical (condition), my preparation, is the same. I feel good, feel confident.
"But obviously as we know, golf is a tough game and you can win the week before and then miss the cut the next week.
"I don't really look at it that way. I just look at it as it's a different year, getting older, different conditions. So who knows how I'll play. I could miss the cut; I could win. You never know what's going to happen."
One thing that Watson does not want to happen again is a repeat of his decisive shot from the trees on the second play-off hole last year, when he hooked a pitching wedge around 40 yards and onto the green.
The resulting par secured victory over South Africa's Louis Oosthuizen but Watson resisted the temptation to revisit the scene of his great escape when playing a practice round with his wife Angie on Sunday.
"There's a funny story on Sunday when me and my wife were playing," he added.
"We were coming down off the 18th tee and there was a group of guys over there, three guys over there (on the adjacent 10th hole).
"I couldn't see who it was and I yelled at them and I said, 'No, that's not the spot, it's a little over.
"I was just joking with them, and they saw it was me. And I come to find out it was Billy Casper (the 1970 champion) and his son. I didn't know that because I couldn't see through the trees."
