"For a while there, we said, 'Let's birdie them all,'" North said. "That's sort of what you have to do. You make three pars in an event like this and eight teams go past you."
During the opening run of birdies, Watson sank a 25-foot putt at No. 3 and North chipped in at the sixth.
"You have to make a lot of birdies to win this thing," Watson said. "You'll probably have to shoot about 62 every day."
Watson, who won the Outback Steakhouse Pro-Am last week in Florida, shot a 62 with his own ball and picked up twice when makable birdie putts were not needed. He made the team's final birdie with an 8-foot putt on the par-3 17th.
The teams of R.W. Eaks and Bob Gilder, Keith Fergus and Wayne Levi, Morris Hatalsky and Don Pooley plus John Cook and Joey Sindelar, were 10 under on the island course in the middle of the Savannah River.
Watson and North, who have played 126 consecutive holes together without a bogey, teamed to win the Raphael Division the last three years, but it was always unofficial money. Not any more.
The Legends Division of the tournament, an individual affair since 2002, switched back to team play this year and declared the earnings would be official money in the annual rankings. Several players like Watson and North jumped right in.
"I've campaigned for this for years," North said. "A lot of players wanted this. It's a lot of fun. And a look at how strong this field is shows I was right."
Their 59 was the best best-ball score ever on this course. The record on the 50-and-over circuit is 58 at Barton Creek Country Club in Austin, Texas, by Al Geiberger and Harold Henning in 1991.
