Longines Tank - 10K White Gold Filled, Black Dial

Longines TV Case | 10K White Gold Filled | Black Dial | Guilloche Bezel | 1970s Description This is one of the rarest Longines configurations we have encountered. A TV-shaped case in 10K white gold filling with a textured guilloche bezel is not something you see in regular vintage watch searches. The combination of white gold, the architectural case shape, and the intricate bezel texture creates a watch that has genuine presence on the wrist. The black dial keeps the focus on the case design. Applied steel block indices provide the necessary contrast for legibility, while the dial itself stays clean and dark, letting the white gold and guilloche texture do the talking. The Cal. 6942 movement inside handles timekeeping duties reliably. On a black croc-embossed leather strap, this watch feels like a piece of jewelry as much as a timepiece. The guilloche work on the bezel catches light from every angle, creating a visual depth that flat bezels simply cannot match.

Historical Significance Longines has a history that stretches back to 1832, and during the 1970s the brand produced some of its most visually distinctive designs. TV-shaped cases were a signature of the era, but versions in white gold filling with guilloche bezels were produced in extremely limited numbers. The guilloche technique involves engraving a repeated pattern into the metal surface, creating a three-dimensional texture that interacts with light. This level of decorative craft on a case bezel is unusual for production watches and places this piece in a category reserved for special-edition and high-end references. Ultra-rare Longines with a combination of materials and finishing that we have not seen repeated. A collector's piece that stands completely apart from typical vintage dress watches.
