How can you tell if a Longines watch is real?

To tell if a Longines watch is real, get a magnifying glass and look for small numbers positioned below the 6 o'clock hour marker. Featured on most of the brand's luxury timepieces, these numbers correspond to the movement and plate numbers. By comparing these numbers to information published on trusted online resources, you can spot inconsistencies that may indicate your piece is a replica. If you don't see any numbers, find out if Longines added them to your particular watch. If so, the lack of numbers may mean your watch is counterfeit. Another method of authenticating is to inspect the entire watch for uneven finishes, low-quality hardware or other imperfections, as authentic Longines watches will be free of these types of defects. Consult a certified appraiser or other knowledgeable expert for a professional opinion on your watch's authenticity. Find a diverse assortment of Longines watches on 1stDibs.
