This is a super rare Longines Flying Saucer from 1938, only the second I ever saw! The steel 32,5mm case has it's lugs hidden under the case hence the name... The original dial is stunning, gloss black with enlarged gilt numerals. Movement is Cal. 10.40 which is working perfectly. It comes with an Extract of the Archives stating it was sold in Poland at the end of 1938. Attached is a perios style pigskin strap with Longines buckle. Very fascinating watch and great piece of Longines history and the condition is super nice!
