Rarest Ed Heuer Biel High-Speed ​​Flak Artillery Column Wheel Chronograph

Ed Heuer's super rare, almost unique high-speed column-wheel chronograph, probably for military use in artillery or air defense. The hand completes a full rotation every 6 seconds.

In 30 years of collecting military watches, I have never seen anything comparable. Even "military watch pope" Konrad Knirim says when asked "I can't say, I've never seen anything like it."

The intertwined dial scale is reminiscent of the World War II anti-aircraft stopwatches with individual paper dials from Carl Zeiss Jena, hence the suspicion of anti-aircraft or artillery. In any case, this is a very, very special and extremely rare piece of military timepiece, one that not even Konrad Knirim can identify.

Apparently, the precision high-speed movement and the exceptional dial incorporate elements of both the early Heuer Semikrograph of World War I and the anti-aircraft stopwatches from Carl Zeiss Jena in World War II.

It may be a test prototype for presentation to the Bundeswehr or other European armies

Description:

Case diameter: unusually large 55mm, onion crown, two-cover case with inner movement protection cover, absolutely unusual, intertwined dial

The column wheel chronograph high-speed movement of unknown caliber bears a Heuer signature, a patent mark and the movement number 134504

This magnificent piece of watch history runs continuously (accuracy not tested, date of last service unknown)

We would be grateful to any friendly expert for any information about the watch and patent, and where it was used. We will then publish the relevant information here in the description.
