The Digital Clock Tower is the first of its kind in North America and will initially provide Tiffany & Co with a platform to promote its new men's timepiece collection.
The Tower is an iconic four-sided digital platform at the centre of this new international terminal.
This high-definition digital structure stands 72-feet tall. It reaches all departing travellers and dominates the terminal's great Hall.

Jean-Francois Decaux, Co-CEO of JCDecaux, notes "We're delighted to expand our US partnership with Tiffany & Co.to Los Angeles International Airport. This new, digital spectacular tower provides unparalleled exposure for one of the world's most iconic brands."
