A Vacheron Constantin tank-shaped wristwatch crafted in 18k yellow gold, featuring a black dial double-signed by Hermès — a distinguished marker of its original retail through the storied Parisian maison. Though the dial displays light patina, it does little to detract from the rarity of this double-signature example.

On the back, its original Swiss-made case is stamped with additional French Eagle’s Head hallmarks and engraved with both the Vacheron Constantin case number (521XXX) and Hermès stock number (555XX), further underscoring its dual provenance.
