Eberhard & Co. Pre Extrafort Chronograph SS Black Snail Dial 1930s

This exceptionally rare Eberhard and Co. Pre‑Extrafort Chronograph hails from the 1930s and stands as a remarkable testament to early Swiss chronograph innovation. Its oversized 40 mm stepped steel case, substantial for its era, frames a striking black gilt “snail‑scale” dial with telemeter outer track—an aesthetic and technical rarity that commands attention. Powered by the in‑house manual‑wind caliber 16000 (Valjoux 65 base), this piece features Eberhard’s ingenious slide‑lock chronograph mechanism, a sophisticated early solution to prevent accidental actuation. The gilt Breguet numerals and central snail tachymeter layout speak to both functional clarity and period elegance, while the fixed‑lug design retains its original character and encourages use on period‑appropriate straps. Collectors prize this model for its combination of technical ingenuity, historical significance in the evolution of chronographs, and its bold presence on the wrist. It remains one of the most sought‑after vintage Eberhard chronographs, offering both mechanical pedigree and a visually compelling dial that has aged with compelling patina. Excellent Condition with European Watch Company leather travel pouch.
