This morning I ran across an article about some watches and there is one that caught my attention. It is a Vacheron Constatin Mercator America and it is a beautifaul watch. A bit pricey, but if I ever have $47.500 that I don't need, maybe I'll get it some day.
The hands of the clock represent what are called nautical dividers and are used by navigational officers to quickly determine distance on a maritime chart.
Here is my attempt at recreating the design of this watch in Silverlight: Vacheron Constantin Mercator America watch experiment.
