Matthew Fitzpatrick beat Scott Hend in a play-off after a thrilling final-day battle to win his fourth European Tour title at the Omega European Masters last September.
The Englishman came into the final round at Crans-sur-Sierre Golf Club four shots behind Hend after dropping a shot in the final three holes of his third round on Sunday morning.
He had caught Hend by the eighth and when he birdied the 14th, 15th and 16th, he had a two-shot lead before a bogey on the penultimate hole left him back in a share of top spot at 14 under.
Hend lost this event in a play-off to Alex Noren in 2016 and he suffered more late heartbreak in the mountains, with Fitzpatrick parring the third extra hole to take the title.
Hend missed a six-footer for victory on the second trip back up the 18th and when the Australian found sand off the tee and went through the back of the green with his second, a par was enough to hand Fitzpatrick victory.
"I'm delighted," he said. "It's one that I've always wanted to win. I love playing this golf course, from the first ever year I came as an invite in 2014 it's one that has really stood out on my schedule and I always want to come back and play.
"I was saying to (caddie) Jamie, 'I think 17 might have cost us today' but it's just one of those things. It's never nice to see but we kept our nerve and just played really smart all week.
"I remember being here in 2015 when Dan won and his parents were there to see him win so it's nice to have mine here too. It's the third win they've seen me achieve so it's pretty special."
