Its impressive 54.4 mm stainless steel open-face case immediately conveys the instrument-like character of the watch, while the keyless-winding construction reflects the advanced technical standards achieved by Eberhard during this remarkable period. Preserved in outstanding condition, it remains an exceptionally well-maintained example of an important historical chronograph. The untouched original dial is the true highlight of the watch. Large Arabic numerals provide outstanding legibility, complemented by elegant heat-blued steel hands. The layout is perfectly balanced, featuring a small seconds register at six o’clock and a semi-instantaneous 30-minute chronograph recorder at twelve. Technically, this timepiece is equally remarkable. The 1/5-second chronograph is activated through the pusher integrated into the winding crown, while the dial incorporates both a tachymeter and a telemeter scale, making it a highly sophisticated precision instrument designed for military, scientific, and sporting applications. A particularly rare feature is the olive-shaped safety locking bolt at approximately 1:30, allowing the user to lock the chronograph functions against accidental operation — a solution found only on a limited number of high-grade professional chronographs of the era. Complete with its original Eberhard presentation box, this outstanding pocket chronograph is an exceptional collector’s piece, combining historical importance, technical sophistication, and remarkable originality in one of the finest surviving examples from the 1930s.
