David Buisson – who once targeted the home of Lord Alan Sugar – stole 159 watches worth £1.4m from a store in the shopping centre in February last year.
He was sentenced last July but appealed against his sentence at the Court of Appeal.
It was argued on his behalf that the sentencing judge did not give enough weight to his claim that Buisson had committed the burglary under pressure from his now deceased co-conspirator.
Buisson also claimed that he was now remorseful and determined to build a new life.
Judges dismissed his appeal, concluding that his sentence of six years and one month imprisonment was not manifestly excessive.
Buisson, wearing a facemask and a high-vis jacket, was driven to the scene by his partner-in-crime in a Mercedes GLA fitted with cloned number plates.
He accessed a service area before climbing onto the roof with a telescopic ladder and breaking into a store.
After bypassing several security systems, Buisson forced his way into a secure area and looted the watches from a safe.
An alarm had already been triggered, and staff discovered the burglary shortly after, alerting Kent Police.
Detectives identified the Mercedes used and found it had passed an ANPR camera in Dartford with a different registration after the break-in.
Insurance checks linked the vehicle to Buisson’s accomplice and investigators later discovered the same car had made more than ten visits to Bluewater between mid-January and the night of the burglary, often with false plates.
Buisson and the other man were charged with conspiracy to commit burglar but his co-conspirator died in prison before he went on trial.
Buisson later pleaded guilty to the offence.
