Military Issued Heuer Pilot’s "Bund" Bundeswehr Chronograph "Small 3H"

The Bundeswehr chronographs were a general Issue chronograph for a number of military forces which included the German Federal Defense Force throughout the 1960s and 70s. Trying to identify and categorize Heuer Bunds is quite the difficult task. Long story short, there are well over two-dozen dial variations to account for. To the untrained eye, many of the dials seem to be the same, but as it goes with collecting vintage watches in general, the devil is in the details. The most recognizable variants to collectors feature an encircled “3H” stamped on the dial, which is an abbreviation for hydrogen-3, a luminous material many of us know as tritium. This is a rare and sought-after model that is becoming highly collectible due to its wrist presence and military history additionally the manual winding Valjoux caliber 234 movement is a proven and robust workhorse of a movement
