Longines "Tank" This model was produced for the American market in the late 1930s (the movement, with its Longines serial number, dates back to 1938. However, to save on taxes and customs fees, the watches were assembled and adjusted directly in the United States, so it's not always possible to be precise about the dating.) Beautifully crafted case with movable lugs, 10K gold-plated, and in excellent condition (86 years old). Honestly, one of the most elegant watches ever up for sale on my shop.
