The world number 66 finished with an eight-under par total. Levy began the final day a shot behind Alvaro Quiros but had three birdies and a bogey in his first eight holes.
He bogeyed the 16th but birdied the 17th to secure his fifth European Tour title.
“It feels so good,” said Levy, who defends his Volvo China Open title this week. “I’m a little bit tired now because it was really tough but I did a really good job. For me, I played an amazing game and I’m so happy to win this trophy.”
The win takes Levy, 27, to ninth in the European Ryder Cup points standings and also inside the world’s top 50, which could also secure him a place at the Players Championship and US Open.
