Who owns one ? Any out there with collectors ? The Automatic Bund cal 12 was unfortunately to expensive...
I have heard a handfull prototypes were made...
Text and Pic from Walter Mannings Bund story:
While the Sternzeit Reguliert is impossibly rare, this is arguably the most rare of Heuer Bundeswehr chronographs: a unique prototype powered by the Caliber 12 automatic movement. This was submitted to the Bundeswehr for consideration, but never adopted. This amazing piece is owned by Gerd R. Lang, owner of Chronoswiss and formerly an engineer with Heuer.
