Two men are set to appear in court charged with robbing the upmarket Selfridges department store in central London.
Connor Groake, 19, and Sam Curtin, 24, both from Islington, north London, are accused of conspiracy to rob and aggravated vehicle taking.
The evening smash-and-grab attack, in which a six-strong gang dressed in burkas made off with £1 million of luxury watches, took place last month.
The gang used the garments to disguise themselves and the tools they were carrying during the raid, police said.
The axe and sledge hammer-wielding raiders smashed glass cabinets at a pre-arranged moment then filled holdalls with the watches.
Stunned onlookers in Oxford Street, the capital's busiest shopping district, watched as the gang met accomplices outside in getaway vehicles believed to be a moped, two motorbikes and a black BMW estate.
The pair, who are in custody, will appear at Kingston Crown Court.
