Watar swooped late and fast to land the Prix Maurice De Nieuil at Longchamp today.
Ted Spread, one of three British-trained runners, set out to make all under Olivier Peslier in the one-mile-six-furlong Group Two heat.
He set a sensible pace up front and Mark Tompkins' runner was still in front at the top of the straight.
However, the challengers were lining up in behind and Davy Bonilla got a dream split aboard the Freddie Head-trained Watar, launching his run between Ted Spread and fellow British runner Times Up.
That kick proved to be decisive as the home-trained runner edged out John Dunlop's Times Up into second.
Shamanova also finished to good effect to take third place with the game Ted Spread having to settle for fourth.
Michael Bell's Allied Powers was fifth.
