Eberhard Pre Extra Fort 40mm - Black Enamel Dial

Old Eberhard chronographs with black enamel dials are among the rarest of their kind. This exceptional example from the 1940s features not only a rare dial, but also a stainless steel case measuring 40 mm in diameter - a remarkable size for a time when most timepieces were less than 36 mm in diameter.

The early Eberhard chronographs are known for their exotic and highly complex multi-scale dials. This model features a telemeter scale on the outer track and a rare tachymeter snail scale in the center of the dial. The deep black dial is accentuated by enameled white markings, which together with the second and minute scales and the sub-dials, create a detailed and technically sophisticated look.

Another special feature is the rare and groundbreaking movement, which was one of the first chronographs to allow intermediate time measurements without resetting and restarting the chronograph. While the pusher at 2 o'clock controls the classic start, stop and reset functions, the lower pusher at 4 o'clock serves as a slide. The chronograph is stopped by simply pushing it up towards the crown and seamlessly resumed by pushing it down. In addition, the slide in the upper position blocks the upper pusher to prevent accidental operation - a remarkable technical refinement for the time.

Combining technical innovation with a highly aesthetic design, the Eberhard Chronograph is a very collectible timepiece that will attract everyone's attention.
