Brametot got up in the shadow of the post to grab Classic honours in the Abu Dhabi Poule d'Essai des Poulains (French 2000 Guineas) at Deauville.
Cristian Demuro delivered the Jean-Claude Rouget-trained colt with a dazzling late run to collar Le Brivido.
The field split into two groups in the early stages with Salsabeel and Rivet leading the far side, and Orderofthegarter prominent on the near side.
Though they came closer together in the last few furlongs, Brametot was nearest to the stands rail having been conserved for a late dash after an unsatisfactory start.
Andre Fabre's Le Brivido looked like maintaining his 100 per cent record, but Brametot - in whom Al Shaqab Racing recently purchased a share - got him on the line.
The Frankie Dettori-ridden Rivet was third for William Haggas, who sent out Sea Of Grace to be second in Saturday's French 1000 Guineas.
The Aidan O'Brien-trained pair Orderofthegarter and Peace Envoy both failed to land a serious blow with the former one of the first horses to come under pressure before staying on into fifth and the latter never getting into contention when coming home in 10th.
FRENCH DERBY TARGET
Al Shaqab's racing manager Harry Herbert outlined the likelihood of a French Derby bid for Brametot.
He said: "That was fantastic. Jean-Claude absolutely loves this horse and said he would improve a lot for his last run.
"He was given a beautiful ride and is trained by a genius.
"From everything he did just then, you'd have to say he's a (Prix du) Jockey Club horse in the making."
Rouget said: "It has been very hard with the virus in the yard but this horse was not in the problem barn, or else he wouldn't be running.
"He has an outstanding pedigree and I think he is a right horse for the Jockey Club."
