The Nav B-Uhr—short for Beobachtungs-Uhren (observation watches)—were originally developed in the 1930s for German military aviators, particularly navigators who relied on precise timekeeping for flight navigation during WWII. These timepieces became legendary for their oversized cases, highly legible dials, and unwavering accuracy, ensuring their place in horological history.
