The men took a bag full of jewellery worth more than $160,000.
Security footage provided from within the store shows only the second man also had a duffel bag.

Police confirmed on Monday one of the men was armed with a shotgun.

Police investigating the incident have since arrested a 41-year-old man, who will appear in Manukau District Court on January 18.
A spokesperson said the man was facing charges including aggravated robbery and presenting a firearm.
While the men were inside the store, Jordan seized an opportunity to run away, slamming the door on the face of the man armed with the shotgun.
The offenders quickly followed Jordan out, fleeing the scene after taking their fill from one of his jewellery cabinets on a moped - except it wasn't that easy for them.
Jordan said as the men tried to take off, the man driving the getaway moped let the clutch off too quickly, forcing the front tyre to lift off the ground.
The moped was later found in the nearby East Tāmaki area, Counties Manukau CIB detective senior sergeant Veronica McPherson said on Monday.

Jordan said the work the police had done and mall security had been of the highest standard and he was very impressed.
"They have done a fantastic job," he said.
Never in his life had he experienced anything like this, not even in Johannesburg where he worked as a merchant for years, Jordan said.
Jordan has offered a $5000 reward for information in relation to incident.
A police spokesperson said their inquiries were ongoing.
"Anyone who has information that may assist our inquiries and has not spoken with police is asked to come forward," they said.
"They can contact police on 105 quoting the file number 210110/5931 or Crimestoppers anonymously on 0800 555 111."
