It's no mystery why Longines is so highly regarded, but if you are in doubt follow this link https://www.longines.com/#!/company/history/19th/1832 to their history, it is a long one! The manual wind movement in this watch uses 17 jewels to accomplish all its functions and it is in fantastic condition . The case is stainless steel measuring 38mm in diameter (not including the crown) by 47mm lug to lug, by 13.5mm thick. Yes, these are great proportions for a very handsome watch with the ability to display time against a perfectly aged black dial. Not only does the dial look great but this watch also has a rotating elapsed time bezel that is in great condition. There are no dings or gouges here. This was a wonderful looking watch back in 1966 but today it looks even nicer with the perfectly aged creamy markers. Anyone who saw you wearing this watch wanted to grab your wrist for a closer look. I dare say that this will still happen today. We here at Father Time Antiques have all admired the styling and cool quality this watch has. Now just imagine it on your wrist! The condition is impeccable and it is winding, running, and keeping time just as it did back in 1966 when this killer watch left Switzerland and headed for the USA. Remember all of our timepieces come with our famous one year warranty for parts and labor so that you may buy with confidence.
