The Eterna Calibre 1492 stands as a pinnacle of mid-20th-century Swiss chronograph engineering, captivating vintage watch enthusiasts and hobbyist watchmakers with its robust construction and timeless reliability. Produced primarily in the 1960s and 1970s, this manual-wind movement powered iconic models like the Eterna 154 FTP chronograph, often featuring reverse panda dials. Its Valjoux 72 base—specifically the 1492K variant—delivers precise timekeeping and flyback functionality, making it a favorite for restoration projects due to abundant spare parts availability.
Historical Context
Introduced during Eterna’s golden era of sports chronographs, the 1492 emerged amid competition from Omega and Rolex. It powered durable dive and racing watches, prized for shock resistance and serviceability. Collectors value its column-wheel design, which ensures smooth pusher operation absent in cheaper cam-lever alternatives.
