Calatrava Ref.6374Q onyx indexes

The Vacheron Constantin reference 6374Q is a notably rare and sophisticated example of the manufacture’s mid-century automatic watchmaking. Executed in 18k yellow gold, this model follows a classic aesthetic characterized by its clean lines and elegant, integrated lugs.

The case remains in good vintage condition and retains its original signed crown. While it has undergone polishing in the past, it has been handled with care to ensure the watch maintains its distinctive structural presence without being over-thinned. The gold surfaces show light, honest superficial scratches consistent with its age.

The dial is distinguished by applied gold indices and a matching handset, both originally featuring black onyx inlays. Upon close inspection, particularly under magnification it is possible to note that the onyx inlay has partially chipped or is missing from a few of the small indices. The hands also display a natural oxidation, a common characteristic of original components from this era. Some minor imperfections are visible on the tension ring surrounding the dial, along with faint circular marks near the center arbor where the hands meet the dial.

Powering the watch is a high-grade automatic movement, which has recently benefited from a full professional service. The movement features a heavy 18k gold oscillating weight for efficient winding; while the rotor exhibits a slight amount of play typical for this specific caliber's construction, it remains fully functional and reliable. This reference 6374Q represents a rare opportunity to acquire a technical and aesthetic cornerstone of Vacheron Constantin's heritage in an honest, serviced state.
