Overall, the watch is in excellent condition. The black glossy dial has developed a rich tropical patina. It shows a gradient from magma red to dark brown depending on angle and lighting condition. One of the nicest dial patinas we have ever seen. The watch case appears to be polished, preserving the design very well. The watch is in good running condition, recently exchanged batteries, keeping accurate time. The watch was bought from a gentleman in Berlin, Germany.
