At the end of 19th century, Webb C. Ball established a system of time standardization for use by railroad companies in the United States. Ball Watch becomes the forerunner of the chronometry standard, meeting the highest standards of reliability and precision. This AeroGMT II model is within the Hydrocarbon collection, which are their toughest watches. It features Ball's proprietary crown guard system that protects the crown from being accidentally damaged and also ensures that the crown is fully secured.
I found Iguana really friendly, helpful and efficient to both buy the pen and when I had a query - very quick to respond. The pen is gorgeous and I’m now using it every day.
