Rectangular shaped watches typically have more of a vintage take on the design. Most of them resemble some of the earliest wristwatches that were made. Because of the sophisticated look of the shape, it's not suprising to find them as dress watches. While many watch brands produce rectangular shaped watches, there are a few that have stood out from the beginning. Two of the most popular and best known rectangular shaped watches are the Cartier Tank and Jaeger-LeCoultre's Reverso.
