Vacheron Constantin 86020 (Pre-owned - Good) — USD 29,500 on eBay

The Reference 86020 represents Vacheron Constantin's approach to combining chronograph and perpetual calendar complications within the Patrimony Traditionnelle series. This model integrates dual high complications in a classical dress watch format, positioning it among the manufacture's complex timepieces. The 43mm case is crafted from 18k rose gold and houses a manual-winding movement. The silver dial provides the backdrop for the chronograph and perpetual calendar displays. A sapphire crystal protects the dial, while the case offers 30 meters of water resistance. The fixed bezel maintains clean proportions appropriate for the dress watch category. This reference appeals to collectors seeking mechanical complexity in traditional packaging. The manual movement requires regular winding, connecting the wearer to the timepiece's operation. The combination of perpetual calendar and chronograph functions, along with the precious metal construction, places this model within the upper tier of the Traditionnelle collection for those prioritizing horological complications over sports functionality.
