The European Tour posted an interesting video of Bryson DeChambeau discussing shot selection with his caddie during a practice round ahead of the Saudi International, where he put his clock system into action.
The reigning US Open champion uses a clockface system when hittign iron shots to determine how far he hits certain clubs.
He treats his swing like the face of a clock and will take the club back to a certain point, as if if is stopping on a specific number of a clock.
It's a system that has become increasingly popular over the past few years and one that DeChambeau has been relying on for a long time.
During a practice round ahead of this week's Saudi International, the European Tour posted a few clips of DeChambeau on their Instagram page, where golf fans were able to listen in on his pre-shot process.

"Can't believe he turned down the cookie. Thought he's trying to bulk," joked one golf fan.
"I really dig his vibe! Real smart!" said former cricket star and huge golf fan Kevin Pietersen.
DeChambeau got off to a great start in Saudi Arabia and shot a 5-under par opening round on Thursday, four shots behind leader David Horsey, who equalled Dustin Johnson's course record of 9-under par at Royal Greens Golf & Country Club.
