B-Uhr: The Watch Every German Pilot Was Ordered to Wear

A wartime navigation tool, a state-issued instrument, and one of the most influential watch designs ever made — the B-Uhr is far more than a “pilot watch.” In this episode, Mr. Watchman dives into the remarkable history of the German Beobachtungsuhr: why the Luftwaffe demanded it, how bomber navigation depended on it, why it had to be 55mm wide, and how five manufacturers — A. Lange & Söhne, Laco, Stowa, Wempe, and IWC — answered one of the strictest watch specifications ever written. From dead reckoning and celestial navigation to hacking seconds, radium dials, oversized onion crowns, and pocket watch movements inside giant wrist cases, this is the story of a precision machine built for war… and later transformed into a grail collectible. ⌚✈️ You’ll also see how the B-Uhr shaped the DNA of the modern pilot watch, and why original examples now command huge prices at auction.
