The Omega European Masters is the Swiss stop on professional men's golf's European Tour, and in 2009 it became the first event in Europe to be co-sanctioned by the Asian Tour.

During the 1971 event, Baldovino Dassù became the first player to score 60 for 18 holes on the European circuit.

The tournament has been held at the Golf-Club Crans-sur-Sierre at Crans-Montana in Valais since 1939, and is currently played in early September each year.

In May, 2006, Michelle Wie, who had a sponsorship contract with Omega, accepted an invitation from the company to play in the 2006 tournament, making her first attempt to play on the men's European Tour.

European Tour executive director George O'Grady said on September 8, 2006 that Wie's appearance was "an experiment" and he would need "a lot of persuading" before inviting Wie to participate in such an event again, despite record crowds estimated at 9,500.
