Product no. A-6728
Manufactured in the early 1940s, this is a Longines timepiece featuring the Caliber 25.17 movement. It boasts a step design and a rectangular model, making it a rare piece with a beautiful black gilt dial. The scarcity of the black gilt dial, considering the era of manufacture and the rectangular case, contributes to its excellent preservation, with a glossy black mirror finish and a rainbow-colored film that adds to its splendid condition. The stay-bright case preserves sharp edges throughout, and the in-house Caliber 25.17 movement, in an angular shape, shows minimal signs of aging. With its recommendable qualities, including suitability for both collection and everyday use, this watch is a valuable addition.
