Vacheron Constantin 42042/423A Overseas SS Black Dial

This Vacheron Constantin Overseas reference 42042/423A is a refined expression of the Maison’s first-generation integrated sports watch, tracing its lineage to the iconic 222 of 1977. Crafted in stainless steel with a 37 mm case and matte black dial, this model was produced around the turn of the millennium and houses the automatic caliber 1311—a COSC‑certified successor to the 1310, offering a 46‑hour power reserve, hacking seconds, quick‑set date, and 150 m water resistance. The design features a notched bezel subtly echoing the Maltese cross, a screw‑down crown, and a solid caseback engraved with the Amerigo Vespucci—underscoring the Overseas’s spirit of travel. Its integrated “brick‑style” steel bracelet with double‑fold clasp offers both comfort and architectural elegance, a hallmark of the era. Collectors prize this reference for its understated military character, technical pedigree, and place as a foundational Overseas model. The combination of COSC precision, robust yet elegant finishing, and historical relevance within Vacheron Constantin’s sports line makes this piece a quietly iconic and highly collectible timepiece. Excellent Condition with Vacheron Constantin box and papers dated 2001.
