The hitman's second goal in five fabulous festive days was enough to keep Kilmarnock thundering along in the top six.
Watkins' sharp first-half finish was his sixth goal of a campaign building brilliantly for the Ayrshire high-fliers.
Neither manager felt the game was going to be on in the afternoon due to the hammering rain but Derek McInnes was sure glad it was.
The Killie manager was able to extend his outstanding record as a gaffer against Saints and see his team bag a fourth win in five games in the process.
However, as McInnes celebrated, counterpart Stephen Robinson must wait for a torrent to abate.
The Saints boss suffered as his side's poor sequence stretched to just two wins in 11 games.
Once again, a lethal touch was missing as they drew a blank and, when goals aren't coming, it takes one defensive lapse to kill you.
In their current mood, Killie were just the team to sniff one out and Watkins made sure he was clinical when it came about.
Over the piece, Killie deserved it and their jubilant fans were singing about going to Europe at full-time.
