Longines 13ZN Non-Flyback Chronograph

About this reference

The Longines reference 3474 was produced during the late 1930s and 1940s, featuring the 13ZN manual-wind movement. While the 13ZN is widely recognized for its flyback complication, the reference 3474 is a rare non-flyback execution of the caliber. Collectors prioritize this reference for its 18k yellow gold stepped case, which typically measures approximately 32.5mm to 33mm, and its multi-scale dials often featuring tachymeter and telemeter tracks. The non-flyback variant is significantly rarer than standard 13ZN models, as the movement was modified to remove the permanent reset function. On the secondary market, these gold chronographs generally command prices between $15,000 and $30,000 depending on dial originality and case sharpness. A notable production detail is that many 3474 examples were delivered to the Italian market through the retailer Oltramare, often featuring distinctive sector or two-tone dial configurations that increase their valuation at auction.
