The 36-year-old defender is leaving Stamford Bridge at the end of the season after 22 years at the club.
With the title wrapped up at West Brom on Friday, boss Antonio Conte handed the club captain his 716th Blues appearance.
And the former England skipper was certainly in the thick of the action, at both ends, as Chelsea ran out 4-3 winners.
Here, Press Association Sport runs the rule over Terry's performance.
RECEPTION
Captain, leader, legend, as the banner in the Matthew Harding Stand proclaims, Terry received a huge cheer from the home fans as his name was read out before kick-off
In his pre-match programme notes, Terry wrote: " I can't tell you how important it is to me to have the chance to celebrate my fifth Premier League title at the end of my last season as a Chelsea player."
EYE FOR A GOAL
Terry has never been backwards in going forwards and dutifully trotted up the pitch for Willian's corner in the 22nd minute
When Watford fail to clear the cross it was only going to fall to one man and Terry swept in his 67th Blues goal
Cue a teary-eyed, badge-thumping celebration
The centre-half has now scored in each of the last 17 Premier League seasons
CASE FOR THE DEFENCE
However, just two minutes later Terry blotted his copybook with a mistake which gifted Watford an equaliser
As the ball looped up Terry and Nathaniel Chalobah got in each other's way
The skipper naturally took control of the situation but ended up heading the ball straight to Etienne Capoue, who nodded a leveller over Asmir Begovic
FITNESS
Terry is keen to continue his playing career, and while the engine has a fair few miles on the clock he has maintained an impressive level of fitness despite his lack of game time
This was by no means the toughest test of his illustrious career, but it was no testimonial either
An attempt to nick the ball from the feet of Tom Cleverley, with his head, showed that commitment to the cause is still there
Terry lasted the full 90 minutes and could certainly do a job for someone next season
OVERALL
Sentimental it may have been but Terry's inclusion certainly proved memorable
A fairytale goal followed by a nightmare mistake, but the skipper at least ended up on the winning side on what is likely to be his final start for the Blues.
