There are a lot of watches that are "field-ish" watches. There are the iconic Rolex Explorers, the Hamilton Fields, and so much more. But then there is the Omega Railmaster. I think the Railmaster is the closest thing to a field watch that Omega makes and is "field-ish" with it's lack of date and simple design. Its heritage lies in the tool watch realm deisgned for high magnetic envrioments, but is it a field watch?
