According to the Archives of Longines the present watch was invoiced to the Nederlandsche Horlogehendel in Amsterdam, Holland, on 8 July 1947.
The present watch is preserved in superb condition considering its age and its military purposes. The watch still retains its original ball-shaped crown, designed to allow the winding with aviator's gloves.
This chronograph is a fine and rare example of a stainless steel Longines "stop seconde" pilot's wristwatch. The combination of the unusual and legendary calibre 12.68 Z movement, the exceptionally beautiful original black dial and the excellent overall condition of the case render this watch exceedingly rare.
