The ads, developed by DY&R, leverages the bank's heritage of firsts, including being the first bank to launch touch screen automatic teller machines in Hong Kong in 1981 and the first to launch a website in 1997.
Citibank director of marketing, Angel Ng, said the campaign aimed to "reinforce our brand equity, innovative spirit and heritage, and renew our commitment to promoting innovation and learning".
The commercials underline the point that the bank is second to none in telephone banking, credit card and online services and wealth management.
DY&R client service director, Cyndy Tan, added that the campaign runs the whole year and the activities included "developing products linked to the anniversary, such as a centenary investment fund".
