About the Longines L1.611.63.04
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, a selection of timepieces based directly on the very first Conquest watches. Available in steel, yellow gold or rose gold, these numbered models, issued in limited series, boast the same dials that made the name "Conquest" famous among the general public. And just like the original versions, the case back of these commemorative pieces is decorated with a gold and enamel medallion, the "gold seal of Longines quality".
