Vacheron Constantin Extra-Plate H/F 18-carat gold, equipped with the legendary caliber 1003

VACHERON CONSTANTIN ULTRA-THIN WRISTWATCH (UNISEX) - EQUIPPED WITH THE LEGENDARY CALIBER 1003.

Ref. 6715 - Entirely yellow gold 18 carats 750/000 - Circa 1975/1985.

Overhauled at Antoine de Macédo (Paris) - 1-year warranty - Delivered with original box + archive extract (in progress).

The very essence of Geneva watchmaking chic. A watch conceived as a jewel of elegance and extreme finesse.

Introduced at the end of the 1970s, the Vacheron Constantin Ref. 6715 follows in the great tradition of the extra-flat watches for which Vacheron Constantin, one of the world's oldest watchmakers (founded in 1755), is renowned.

While many watches tell a story, this one tells of the quest for purity, perfect minimalism, and the art of hand-winding pushed to its most refined level.

Its heart beats thanks to the celebrated caliber 1003, one of the thinnest hand-wound mechanical movements ever conceived (1.64 mm thick). An absolute feat of miniaturization, still admired today for its classic architecture and traditional finishes.

With its 27 mm diameter, exceptional slenderness and uncluttered design, this watch is mixed/unisex: a format typical of the elegance of the 70s and 80s, perfectly suited to both men's and women's wrists.

A sober, discreet aesthetic, almost Parisian in its approach: the grace of a watch that seeks not to impress through size, but through the sheer beauty of proportion.
