Vintage Longines Tre Tacche bearing the reference 5182 in a 35mm stainless steel step case. It is fitted with a Longines manually wound mechanical movement, caliber 12.687. It was invoiced on 16 June 1943 to the company Ostersetzer, which was at that time our agent for Italy according to the excerpt from Longines.
The case on this one is so clean. Even the luminous compound looks like it is in good shape.
