"It's always a special feeling when you win a tournament," the 43-year-old said.
"That proves to me that the ball is still going the right way and it's still there."
For the second time in three years, Jimenez was able to snatch a thrilling victory at the Fanling course courtesy of an error by his closest rival on the final hole.
In 2004, it was South African James Kingston who hooked a shot and had to take a drop shot, while on Sunday Swede Robert Karlsson fluffed a chip up a bank at the last to allow Jimenez to claim the title with a closing bogey.
"I feel sorry for Robert with the way it finished, he played so good all week," Jimenez said.
"He had a double bogey at the last, and it's not the best way to finish." Jimenez, who went into the final day in second place four shots behind Karlsson, had a mixed front nine with three birdies and three bogeys.
It was not until the 12th hole that he managed to get any real momentum going and even an eagle at the 13th still left him trailing Karlsson.
"When I made that one, I felt 'well ... a few shots, a few holes to go, keep focused on the shots', and it happened," he said.
Another birdie at the 16th drew him level with Karlsson.
"I commented to my caddie, 'we can go one better, finish on one of these two holes and win the tournament or at least we can have a playoff'," he said.
Despite Karlsson's poor chip at the last, Jimenez took three putts to finish and so left his rival with a final chance to claim a bogey and force a playoff.
"When I missed mine, I still know that I've got a chance because it's not an easy putt and he could miss that one," the Spaniard said.
Jimenez's 14th European Tour title will boost his chances of a fourth appearance at the Ryder Cup next September.
"Of course, I would be very pleased to be on the Ryder Cup team," he said.
"You never know what's going to happen. Just enjoy yourself and every moment."
