The Longines Conquest Calendar Ref. 9005 is one of the most refined vintage dress watches produced by the brand during the golden era of Swiss watchmaking. Introduced in the mid-1950s, the Conquest range marked Longines’ push toward premium materials and advanced mechanical engineering.

This example from 1956 features a solid 18K yellow gold case housing the automatic Calibre 19ASD with date complication—a movement known for its reliability and smooth operation. The silver dial, adorned with a mix of art deco numerals and arrowhead markers, captures the understated elegance of the period. On the caseback sits the iconic blue enamel Conquest medallion, a hallmark of the model and a testament to its originality.
