This is a smaller sized men’s vintage 1955 solid gold Longines measuring 28mm, making it ideal for a man who prefers a subtle smaller watch with 50s style, or a lady who loves a vintage solid gold watch with class! I love the dog-leg angled lugs on the crisp solid 18k. gold Longines case. The dial has aged over the years lending a look that adds a vintage credibility to the watch. The manual winding Longines caliber 23Z movement was just cleaned and is accurate. This watch makes an investment as the gold content certainly adds up.
