The Wenger name has been synonymous with reliability, functionality and quality since 1893. They have supplied the Swiss army with vital equipment for over a century. It is not surprising then that Wenger watches have the same precision manufacture and exceptional design qualities as their knives and tools. The Big Crown Diver as the name suggests has a convex, glass face and is waterproof to 660 ft, making it a valuable and trusted piece of equipment on any of the toughest expeditions.
