Lawton has been tasked with creating a TV ad to drive awareness of Euronics' core values of "superior service and knowledge" while making shoppers aware of its offers available throughout the Christmas and New Year period.
The ads are due to launch in November to run through until the beginning of January.
Lawton is also providing the media planning and buying for the campaign.
Kathryn Portwood, head of marketing at Euronics said: "Lawton demonstrated a superior understanding of our business and is completely in tune with where we want to take our brand.
"Combined with a fantastic creative concept, Lawton really impressed us."
Mark Scott, Lawton managing director, said: "Working with Euronics is an extremely exciting opportunity and we're delighted that our creative concepts and robust planning are in tune with how Euronics see their brand developing.
"We're looking forward to implementing an impactful campaign that cuts through the aggressive Christmas sales period."
