Vacheron Constantin 6378 “Florentine Bezel” – 1970s
White Gold Rarity with Linen Bracelet & Dagger Indices
The Vacheron Constantin Ref. 6378 Q is one of those rare pieces that remind us why the maison sits at the very top of Swiss watchmaking. With its 35.5 mm 18k white gold case, Florentine-finished bezel, and dagger-style hour markers, this piece brings understated elegance to a bold level.
The original silver dial is untouched and flawlessly preserved, while the finely textured 18k white gold bracelet offers a uniquely tactile experience — complete with the Maltese cross clasp.
Inside, it houses the in-house VC Caliber K1071, a beautifully engineered automatic movement with an 18k gold rotor, ticking with elegance and precision. This is a watch that doesn’t shout — it speaks softly with heritage, texture, and craftsmanship.
A seldom-seen reference in stunning condition — quietly extravagant and supremely rare.
