Miguel Layun put the visitors in front inside 15 minutes, but Ross Barkley struck back in the second half to give the Toffees a crucial equaliser.
Substitute Odion Ighalo thought that he had won it for Watford at the death, scoring with less than 10 minutes to play. However, Everton frontman Kone, who scored just once in 21 appearances last term, was on hand to level the scores.
Appearing as a substitute in the 62nd minute, he managed two attempts at goal - one of which hit the back of the net - while also recording an assist.
He also completed 91.7% of his total attempted passes to cap a very efficient attacking display.

Following his involvement, the Ivorian international took to Twitter to comment on what he described as an 'emotional' day.

He also made reference to his elaborate hair colour; the 'goldenhead' that has served him so well in the past.
Prior to his relatively unsuccessful spell at Goodison Park, he had enjoyed fruitful periods with Wigan Athletic and Levante, among several others.
I only dyed it back yesterday. I wanted to show the 'goldenhead' is BACK!!! pic.twitter.com/g5s1qcDSEP— ArounaKone (@OfficielArounaK) August 8, 2015
Perhaps a return to the golden hair could see a new free scoring Arouna Kone at Everton this season?
