1930s Longines Cal.13zn Rare "non Flayback" Chronograph with Pulsation dial in 18K yellow gold

A rare pulsation dial chronograph from the late 1930s, featuring the renowned Longines Caliber 13ZN in an 18K yellow gold case. Despite its compact 34mm size, the solid 18K gold case gives it a substantial weight, and the rare pulsation dial adds a unique and creative expression. This early example of the 13ZN, without the flyback function—a rarity even in that era—is particularly special. While there are signs of aging and minor scratches overall, considering the 13ZN movement, solid 18K gold case, pulsation dial, and non-flyback feature, this piece offers excellent value. Longines' in-house caliber chronographs are legendary in the history of watchmaking and will continue to be highly regarded and appreciated in the future.
