The two men targeted the luxury watch shop near the Champs-Élysées on Tuesday morning at around 11am.
An employee at the store was hit around the head with a club by one of the men before the thieves made their escape from the store on Rue Marbeuf in the city's 8th arrondissement (see map below).
The value of the stolen goods has been estimated at €900,000, a police source told BFMTV.
The men fled the scene on a motorbike, with a passerby capturing their escape on camera (see tweet below).
