Not to sharpshoot, but the B-uhren were kind of an historical deviation. Before then, there were many pilot's watches, including civilian ones in the 1920s and IWC's "special watch for pilot's" in the 1930s among many others. In addition, the UK pilot's watch tradition, culminating in the Mark 11 after WW II, really would claim no base in what the Germans did.
What I say isn't intended to detract from these watches --B-Uhr are rare and special-- but their historical role is limited.
