Ji Chang-wook is more than a global megastar with an uncommon warmth. Since joining the Rado family in 2023, the celebrated actor and singer has proven to be an inquisitive soul with a genuine passion for the artistry of horology.
His journey with the Swiss watchmaker reached a creative peak during a visit to the Rado headquarters in March 2024, where a tour of the high-tech ceramic lab evolved into an inspired collaboration. The result is the breathtaking True Square Open Heart x Ji Chang-wook, a timepiece that mirrors the radiant and harmonious character of the man himself.
The design is deeply personal, incorporating twelve bright red rubies to mark the hours.
For Ji Chang-wook, the choice was symbolic as the ruby is his birthstone, and in Korean culture, the color red is a traditional harbinger of good luck and protection.
Encased in matt black high-tech ceramic with a matching bracelet, the watch features a monobloc construction that ensures both durability and comfort. The open heart dial invites the eye to admire the circular grain decoration and the intricate machinery of the Rado calibre R734 movement as it dances away time in perfect cadence. This movement is not only a visual marvel but also a technical one, boasting an 80 hour power reserve and an antimagnetic Nivachron hairspring for superior accuracy.
Every detail of this limited edition has been considered to reflect an open and honest personality. The inclusion of a smoked sapphire crystal on the sandblasted titanium case back reveals the movement from both sides while showcasing Ji Chang-wook’s signature and the limited edition engraving. The rhodium colored hands are treated with red Super-LumiNova to provide a luminous glow that complements the vibrant rubies.
For the man who wears this model most comfortably in his real life, the True Square Open Heart is the perfect combination of modern shape and raw emotion, crafted for those who appreciate a hint of mystery in their elegance.
