One man built this watch, by hand, in Munich. Nicolaus Spinner machined the case himself from a solid block of German surgical steel, assembled every component personally, and then rated the whole thing to 4,000 meters. The indigo dial on steel bracelet is a serious combination on a watch that was never designed to impress anyone who does not already understand what they are looking at.
