Vacheron Constantin may not be the oldest watch brand, but it does have the claim to fame for being the world’s oldest continually operating Swiss brand. The brand, founded in 1755, is known for its complex high complications and time honored watchmaking. Another of its bragging rights comes from creating some of the most complicated watches ever built. The brand continues to build everything in house in Geneva and offers a variety of models in nearly a dozen collections. The brand is committed to craftsmanship and continues to produce excellent timepieces such as their new Patrimony and Traditionnelle lines.
