When it comes to classic maritime vessels, nothing has a more tumultuous history than the U-boat. Something about being encased in metal, crushing depths, and the occasional mermaid just tickles our fancy. So any company (especially one that makes watches) calling themselves U-Boat better bring their A game, and bring it they did. The Classico U-1001 is the most rugged watch that U-Boat produces and is rated to withstand 1001 meters below the water’s surface. For reference, the Rolex Submariner gets 300 meters. If you’re seriously going underwater, you better get serious about your choice of timepiece. Oh yeah, it also looks damn good.
