Miguel Angel Jiménez, the oldest winner in European Tour history, will return to Crans-Montana for his 25th consecutive Omega European Masters from September 5-8.
The 49 year old Spaniard won the title in 2010 and has ten top ten finishes in total at Crans-sur-Sierre.
After suffering a broken leg in a skiing accident at Christmas, Jiménez has been in fine form since returning to action.
He finished fourth in the BMW PGA Championship at Wentworth, and was the half-way leader in The Open Championship, eventually finishing tied 13th. He was also tied fourth in the WGC Bridgestone Invitational, so will head to Switzerland in good form.
