Pre-Extra Fort Chronograph is a highly interesting and collectible vintage piece, most likely dating to the 1940s. \u003cbr\u003eWhat makes this watch especially noteworthy is its unusual chronograph control system. The upper pusher is used for the chronograph operation, while the lower side control features a sliding function. Once the chronograph is running, this lower slider allows the central chronograph seconds hand to be temporarily stopped and then restarted without resetting to zero. This is a rare and very appealing feature from a collector’s perspective, reflecting the practical, instrument-like nature of early chronograph design.\u003cbr\u003eThe dial is equally attractive and distinctive. It features a multiscale layout, with a black outer scale and a blue scale marked in kilometres (KM). The black scale appears to be a tachymeter-style scale, used for calculating speed over a measured distance, while the blue scale is consistent with a telemeter scale, traditionally used for measuring distance based on the speed of sound. Together, these scales gave the watch a strong technical and sporting character, and make it especially evocative of the golden era of motorsport and professional timing instruments.\u003cbr\u003eWith its balanced two-register layout, elegant applied numerals, steel case and warm vintage character, this Eberhard offers much more than simple timekeeping. It is a rare collector’s chronograph with an unusual operating system, a visually striking dial and strong historical appeal. Historical Context\u003cbr\u003eEberhard \u0026amp; Co was founded in 1887 in La Chaux-de-Fonds, Switzerland. In 1935 the company\u003cbr\u003eintroduced an oversized chronograph that collectors now call the Pre-Extra-Fort. These watches\u003cbr\u003eused the Valjoux 65 as a base movement but incorporated Eberhard’s own modifications: the\u003cbr\u003estart\/stop\/reset functions were consolidated into one pusher at 2 o’clock, and a sliding lever at\u003cbr\u003e4 o’clock locked the pusher. Cases were large for the time (around 38–40 mm) and often\u003cbr\u003efeatured stepped bezels. The dials commonly displayed concentric telemeter and tachymeter\u003cbr\u003escales, sometimes with pulsometer or snail designs. The Pre-Extra-Fort was produced until the\u003cbr\u003eearly 1940s and later evolved into the Extra-Fort line of three-register chronographs.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis watch was last serviced on 04-05-2026.\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"specifications\"\u003e\n\u003cp\u003e\u003cstrong\u003eBrand and model:\u003c\/strong\u003e Eberhard \u0026amp; Co Pre-Extra Fort Chronograph\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eReference:\u003c\/strong\u003e Unknown\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCase material:\u003c\/strong\u003e Steel\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCase size:\u003c\/strong\u003e 39 mm\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLug-to-lug:\u003c\/strong\u003e 47 mm\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThickness:\u003c\/strong\u003e 13 mm\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDial:\u003c\/strong\u003e Original\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCrystal:\u003c\/strong\u003e Acrylic (period-correct)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCrown:\u003c\/strong\u003e Period correct\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStrap or bracelet:\u003c\/strong\u003e Calf leather strap\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMovement:\u003c\/strong\u003e Manual\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCaliber:\u003c\/strong\u003e Valjoux 65\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eJewels:\u003c\/strong\u003e 17\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMovement serial:\u003c\/strong\u003e 1031•••\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEstimated production:\u003c\/strong\u003e circa 1950s\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWater Resistance:\u003c\/strong\u003e Splash Water Resistant (handwashing ok, not showering)\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch3\u003e📦 What’s Included\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eBox\/Case:\u003c\/strong\u003e Secure black travel watch case.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDocuments:\u003c\/strong\u003e Invoice and our service certificate worth €369 — included free of charge\u003c\/p\u003e\n\u003ch3\u003e🚚 Shipping, Returns\u003c\/h3\u003e\n\u003cp\u003eInsured worldwide shipping. 14-day inspection (unused, seals intact).
