This is a highly rare and precious timepiece from the 1940s featuring the Eberhard Caliber 1600 and a split-second chronograph function with 3 registers, housed in a stainless steel, 40mm cylinder-design case. During that era, only a few brands like Patek Philippe, Breitling, Rolex, and Universal were known for using split-second chronograph technology. Eberhard, however, incorporated the Caliber 1600 with split-second and its unique hack function into this model, marking a culmination of their technical prowess.
This three-register split-second chronograph is exceptionally rare, as most split-second chronographs of the time typically had two registers. The watch is in excellent condition, and the 40mm cylinder case, which accommodates the substantial split-second movement, retains its wonderful, unpolished state, showcasing an overwhelming presence.
