The B-Uhren watches guided German bombers in their terrible campaigns of World War II with dropped bombs whistling through air to end in devastating consequence. Bred to equip the military navigator, the B-Uhr remains a marvel of clean design and simplicity.
In the skies over Europe during World War II, German Luftwaffe reconnaissance flights set out to find strategic targets for bombing runs. Plotting the precise locations was the job of the Beobachter, or observer, who used a map, landmarks and a timepiece to identify and plot the targets.
Over the thick sleeve of his leather flight jacket would be strapped a massive wristwatch, precise and easy to read at a glance. This watch was not surprisingly called a Beobachtungsuhr, or observers watch and there were only a handful of companies in Germany authorized by the Aviation Ministry to manufacture them: IWC, Wempe, Stowa, A. Lange & Söhne and Laco. The B-Uhr was essentially a chronometer-grade pocketwatch movement housed in a wristwatch case and fitted with a radium luminous dial. The B-Uhr is easily identified by its distinctive dial with an outer minute track, five-minute marks enumerated and a large arrow at 12, and an inner hour ring that lines up with the hour hand.Unlike many other pocketwatch conversions of the era, these had a center seconds hand. An oversized crown allowed for hand-winding while wearing gloves. Read the whole story here. Contact me for further images if required. I offer the watch only.
