I am sure that mine is a cheap copy, because it was under $10.00 when I purchased the watch. That is what I wanted for a fishing watch, the green nylon band is very durable in saltwater when I get it wet. It is also easy to keep clean and I feel that is an important feature for my fishing watch.I believe American Aviator is the brand.
It's a "fleiger" style watch, which is a pilot style, popularized by the Germans in the early 20th century. There were a handful of brands that made them for the luftwaffe (Laco, Lang & Sohne, IWC, Stowa, and Wempe), and some people try to collect originals from each brand ($$$).
