The Sarawak: Masterlink's origins

In 2007, Gérald Charles Genta designed the Maison's first integrated bracelet watch as an exclusive piece for the Royal family of Sarawak, a Malaysian state. The predecessor of the Masterlink featured a full pavé set bracelet and case in round diamonds and baguette rubies, carrying the DNA of high-end gem setting which now is signature to the Maison.
