Longines FLAGSHIP CLASSIC

Owners praise the Longines FLAGSHIP CLASSIC as a beautiful, classy dress watch with deep brand heritage, suitable for special occasions. One owner noted the stock strap appears narrow due to the lug design, making spring bars visible. The Longines FLAGSHIP CLASSIC reissue is considered a fantastic deal at $700, especially after a recent official Longines service and dial replacement, presenting it as a like-new watch. However, its lack of patina may disappoint collectors who value "character" from wear and scratches. Overall, owners rate the Longines FLAGSHIP CLASSIC highly for its aesthetic appeal and value proposition.
