Shared passion and values
Ji Chang-wook joined Rado in 2023 as global brand ambassador, bringing with him a genuine passion for watches. An international star with warmth and down-to-earth spirit, he is deeply interested and fascinated with the design and craftsmanship behind each Rado timepiece. He particularly appreciates Rado’s mastery of materials, especially high-tech ceramic.
A true connection
Ji Chang-wook has quickly become a valued member of the Rado family, and this close and authentic partnership naturally led to the co-creation of an iconic watch: the Rado True Square Open Heart x Ji Chang-wook.

The pursuit of happiness

For his very own limited edition, Ji Chang-wook chose twelve bright rubies with matching red Super-LumiNova® to mark the hours – evoking good luck and happiness in harmony with Korean cultural traditions. The matt black high-tech ceramic case and bracelet ensure extreme comfort for the wearer. This is a timepiece of exquisite character and undeniable charm, and, like the man himself, a true inspiration from any angle.
