Here’s an impressive and well-preserved first-generation vintage Longines Conquest Calendar Automatic. The Conquest model by Longines is comparable to the Constellation by Omega. The original, unpolished case shows normal wear and scratches but retains its integrity. It features a brand-new acrylic crystal.
The case dimensions are 35mm wide (excluding the crown) and 42.5mm from lug tip to lug tip. The case model number is 9007-3 and it comes with a brand-new 18mm genuine leather strap.
The dial is factory original and exhibits a well-aged condition. The recently serviced automatic movement is the Longines caliber 19ASD, with a movement serial number of 10288059, dating this watch to 1957. Rare and well-preserved vintage Longines watches like this are scarce in today’s market. The wrist size shown in the photo measures 6 inches.
