In 2014,, Longines celebrated the 60th anniversary of the filing of the patent for its "Conquest" brand. To mark this occasion, the Swiss watch company launched its Conquest Heritage 1954-2014. With a diameter of 35 mm, this model in steel displays a sunray silver dial with yellow applied indices. Fitted with the mechanical calibre L633, it indicates the hours, the minutes and the seconds. The caseback is screwed down and decorated with a gold and enamel medallion representing a fish. This timepiece is numbered and limited to 600 pieces.
