During the mid-20th century, Eberhard & Co. gained recognition for its sports watches and chronographs, catering to the growing interest in functional timepieces such as chronographs. The brand's commitment to innovation was further exemplified by the launch of the "Extra-Fort" collection, known for its robust design and advanced features.

From a technical standpoint, Eberhard & Co. made a distinctive choice by outfitting the new model with a Valjoux 65 caliber. Notably, they implemented updated modifications aimed at accentuating its role as a professional instrument. A revolutionary feature for the time was the incorporation of a single push-button for both stopping and restarting the chronograph functions. Therefore, when the complication was active, pressing the pusher didn't reset the seconds sphere to zero but instead initiated a fresh measurement from the beginning.

The present example is preserved in outstanding condition and retains all of its original factory finishes on the case, even its original caseback sticker. To go along with the beautiful yellow gold case, the watch is also equipped with a complementary champagne colored dial. At 40mm, it boasted a truly substantial dimension for its era, providing the dial with a prominent role within the timepiece.
