After its release in 1954, the Conquest line was Longines' most iconic model. 
 
This example is in extremely good shape, with flawless dial, you can see every shade of the two tone as it would look from the factory. The hands have developed a slight patina over time, suggesting it wasn't used much at all.
 
The case is thick, with sharp bevels. The enamel and gold case back medallion is in good shape too, which is usually prone to wear.
 
The watch is powered by the caliber 19As, one of Longines earliest Automatic movements. A real stunner on the wrist.
