Vacheron Constantin's exquisitely designed Mercator wristwatch was released in 1994 to commemorate the 400th anniversary of the scholar’s death, reflecting his legacy through its intricate design. The retrograde hour and minute hands resemble the legs of a handheld compass, while the stunning polychrome champlevé enamel dial features a depiction of China from a map dating to circa 1619. This dial—and indeed, the very concept of the watch—was crafted by Belgian master enamellers Lucie and Jean Genbrugge, who specialize in creating ultra-thin miniature paintings on enamel.

Making its auction debut in this configuration, the dial prominently displays China, along with Korea and a small portion of Japan on the right side. This particular example, made of platinum, is confirmed by its certificate of authenticity as part of a limited edition of only 6 pieces produced exclusively for the Chinese market.

Consigned directly from the original owner, both the platinum and yellow gold variants (the next lot) were purchased at the same time and this particular example has hardly been worn since the early 2000s. The dial is beautifully preserved, with its vivid enamel serving as a true testament to the intersection of history, art, culture and watchmaking.
