This is a special LONGINES from the 1950’s, due to its completely original and extremely clean black dial. It is very uncommon to find such a preserved black dial-having sunken gold toned “Explorer” style dial with original Dauphine hands, inset gold minute markers (like Patek Philippe) and sub-seconds. The manual winding movement was just cleaned and is accurate. This gold filled case is very attractive, with a 34mm. case and extended horned lugs stretching to 44mm. The case back is screwed. I can’t insist how great this watch looks…and all original.
