Longines circa 1913 Pocket/Pendant Watch — 20K White Gold

An exceptional early Longines mechanical pocket/pendant watch dating to approximately 1913, housed in an unusual rectangular 20K white-gold case. This collector piece combines early Swiss horology, substantial precious-metal content, distinctive period design and a signed Longines movement. The manual-wind movement is signed: LONGINES W. Co. SWISS 17 JEWELS 5 ADJ. The movement serial falls within a range associated with approximately 1913 based on published Longines serial references, so the watch is described conservatively as circa 1913. The case is stamped “20K W.G.”, indicating 20-karat white gold. The complete assembled watch weighs approximately 50.44 grams, while the removable rear case panel alone weighs approximately 12.00 grams, both documented in the listing photographs. Based on an estimated 35–40 grams of recoverable 20K gold content, the theoretical intrinsic precious-metal value as of September 21, 2026 is approximately C$5,700–C$6,500 before refiner or dealer deductions. This is provided only as a value reference. Actual recoverable gold weight, purity across individual components and dealer/refiner payout may vary. The entire 50.44 g gross weight is not represented as gold because the watch also contains the movement, dial, crystal and other non-gold components. Importantly, this watch is being offered as a collectible antique Longines timepiece, not as scrap gold. Its horological, historical and collector value should be considered separately from its underlying metal value. The watch features a rectangular period design with faceted corners, a geometric pendant bow and a signed LONGINES dial with stylized Arabic numerals. The dial retains significant original character and shows natural spotting, discoloration and patina consistent with a watch more than a century old. MECHANICAL CONDITION The movement has been tested carefully. After winding, the watch responds mechanically and runs, confirming movement activity. However, it has not been professionally serviced, regulated or tested for long-term accuracy or power reserve. CONDITION: This watch remains in honest antique condition. Age-related characteristics include dial patina and spotting, surface scratches and marks to the case, wear consistent with its age, marks to the rear case panel and natural aging visible within the movement. These characteristics have not been digitally removed or concealed. The photographs are of the actual watch being sold and form an important part of the condition description. Buyers are encouraged to review the detailed images showing the dial, case, movement, hallmarks and documented weights. IDENTIFICATION & ACCOMPANYING TAG: An older handwritten identification tag accompanies the watch and references: White Gold 20K / Longines / 1925 / 302M101186 The tag is included as part of the item’s existing history. However, the handwritten “1925” notation is not being relied upon as definitive factory documentation. The circa-1913 dating used in this listing is based on the movement serial and published Longines serial chronology. An official Longines Extract from the Archives is not currently included. INCLUDED: • Antique Longines rectangular mechanical pocket/pendant watch • Original attached vintage identification tag COLLECTOR APPEAL: What makes this example especially compelling is the combination of early Longines manufacture, circa-1913 dating, a signed 17-jewel movement adjusted to five positions, unusual rectangular architecture, substantial 20K white-gold construction and surviving original aged character. It sits at the intersection of early Swiss watchmaking, jewellery craftsmanship and precious-metal collectibility. The substantial intrinsic gold value provides a meaningful underlying value reference, while the complete Longines movement, period dial and distinctive case make the watch considerably more interesting as a preserved historical object than as metal alone.
