Former champions Richie Ramsay and Thomas Bjorn start well
The duo both replica watches signed for scores of 62 at the par 70 Crans sur Sierre Golf Course and find themselves two clear at the end of a day that saw plenty of players go low.
Ramsay omega replica who finished fourth at the Italian Open last week has previously won the tournament and admitted afterwards he has a liking for the course in Switzerland, at one stage believing he could actually shoot a 59.
"It's a tricky course but if you get on a run, there's definitely a low score be had out there. I played really well two years ago and I was able to draw those good memories on my way round today."
Ryder Cup duoNorthern Ireland's Gareth Maybin and English pair Tommy Fleetwood and Graeme Storm sit together on six under, one ahead of a seven man group that includes Ryder Cup duo Jamie Donaldson and Victor Dubuisson.
Looking for back to back victories after sealing his place on the European team by winning the Czech Masters last time out, Donaldson had four birdies in five holes at one stage on his back nine before finishing off with a bogey.
He and Dubuisson are joined by Englishmen Seve Benson and David Lynn, Northern Ireland's Michael Hoey, Frenchman Raphael Jacquelin and Brooks Koepka of the United states.
Benson is playing in just his second event since May due to back problems; the 27 year old had a broken bone which kept him out of action from the BMW PGA Championship in May until last week.
"I had a fracture in my vertebrae so it was pretty serious," he told Sky Sports.
"Initially I thought it was just a pulled muscle but we had a few scans and I had fractured one of my vertebrae so it was rest time and then some rehab.
"I had to change my swing a little bit and as long as I keeping swinging in the new way then fingers crossed I will be fine, but if I revert to my old swing then it could come up again."
Defending champion Thomas Bjorn, seeking to emulate Seve Ballesteros by winning the event for the third time, rounded off a good day for Ryder Cup captain Paul McGinley with a four under 66.
The 43 year old Dane, who will play his first Ryder Cup since 2002 later this month, said: "You have to play the golf in front of you and not worry too much about what's ahead.
