Longines Automatic Extra Ultra Slim Automatic Swiss Made Vintage 70 Era: 1970s. Self-winding mechanical movement calibre 994.1. (This ultra-thin movement was at that time the thinnest in the world and the last of Longines to be entirely "internal". Its very beautiful finish and high price forced the brand to transfer it to Lemania, which then sold it under the code 8810.) Gold-plated steel case, diameter 32 mm including crown. Champagne dial (see photos). Black cabochon crown (see photos). Pressure-fit case. Sapphire crystal. Date display window at 3 o'clock with quick-set date feature. Integrated leather strap (not Longines). No box or papers. The watch is used and in perfect working order. Insured shipping with tracking via express courier.
