Eberhard & Co. Oversized Chronograph with Black Dial and Radium Index Dial on Steel Bracelet

An oversized Eberhard & Co. chronograph from 1945, cased in a 40 mm stainless steel case and fitted with a striking black gilt "Extra-Fort" dial with radium indices. Eberhard & Co., founded in La Chaux-de-Fonds in 1887, was among the earliest Swiss manufacturers to specialize in chronographs, and the Extra-Fort line represents the house at its most technically accomplished. The combination of a black gilt dial with radium-painted indices is one of the most visually compelling configurations produced by Swiss chronograph makers of the 1940s, offering exceptional legibility and a dramatic aesthetic that has made these dials among the most sought-after in vintage chronograph collecting.

Key Specifications

Collector's Note

The Eberhard Extra-Fort is one of the foundational references in the history of the Swiss oversized chronograph. Produced from the late 1930s through the 1940s, it was designed to meet the demands of professional users who required maximum legibility and chronograph functionality in a robust case. The 40 mm diameter, which was genuinely oversized by the standards of the period, combined with the high-contrast black gilt dial and radium indices, creates a watch of extraordinary visual impact and historical significance. The manual-wind chronograph movement, with its characteristic pushers and register layout, is a direct expression of the watchmaking technology of the wartime era, and its survival in working condition is a testament to the quality of Eberhard's manufacture. This is a watch for the serious collector of vintage Swiss chronographs who understands the importance of Eberhard's contribution to the genre.
