It comes after the Metropolitan Police launched an investigation into three separate incidents across Stratton Street and Brewer Street, Mayfair, on June 25 and June 26 last year.
The three victims were threatened with violence as they attempted to prevent the robbers from forcibly taking their high value watches.
Two of the watches were successfully robbed from the victims.
On July 30, 2024, 35-year-old Tedros Haile of Fulham Palace Road, Hammersmith, 24-year-old Mahad Jammeh of Beaconsfield Road, Enfield, and 27-year-old Christian Whittingham of Granville Road, Uxbridge, were arrested.
Investigating officers recovered clothing worn at the time of the crimes, confirming the links between the men and the robberies.
CCTV footage was used to identify the men as well as a vehicle linked to the men.
Police discovered that the trio had conducted surveillance on members of the public to identify their victims.
Haile pleaded guilty to one count of robbery at Southwark Crown Court on June 25, 2024, and was later found guilty of a further count of robbery and one charge of attempted robbery on February 11.
Jammeh and Whittingham both pleaded guilty to one count of robbery on August 28, 2024. They later pleaded guilty to a further two counts on November 4, 2024.

Det Insp Lizzie Beeston said: “Our investigation has ensured three violent offenders have been removed from our streets.
“Every robbery has a significant impact on the victim. This is a violent crime that leaves a significant, lasting effect on the victim.
“Tackling violent crime in all its forms is one of the Met’s priorities and we are determined to reduce the number of robberies. As part of the New Met for London Plan, localised proactive teams have been set up to deal with robberies affecting our local communities.”
