About this reference
The Longines reference 103, featuring the 13ZN caliber, was produced during the late 1930s and 1940s. Collectors prioritize this reference for its 18k pink gold construction and the inclusion of the 13ZN movement, which was the first chronograph caliber to feature a flyback function. The case typically measures 37mm to 38mm, featuring a stepped bezel and heavy lugs. Dial configurations often include multi-scale tachymeter and telemeter tracks in enamel or metallic finishes. Due to the limited production of oversized gold chronographs from this era, the reference 103 is considered rare. On the secondary market, these watches generally command prices in the mid-five-figure to low-six-figure range depending on condition and dial rarity. A notable 2015 auction result for a pink gold 13ZN with a sector dial reached approximately $100,000, illustrating the premium placed on well-preserved examples with original components.
