This 1960’s Longines is a hard to find vintage watch being very thin at 7mm. including the crystal and a respectable 34mm. across. Thin watches are becoming very difficult to buy these days. The original logo winding crown is present. The narrow bezel makes this watch look even larger due to the all-dial appearance. The dial is all original with some subtle patina, needle-thin elongated markers and hands. The caliber 428 manual winding movement was just cleaned and is accurate. Any patina on this dial is hardly visible with the naked eye and is more visible in my brightly lit close-up photos. I’ve said it many times, I believe Longines watches are currently undervalued.
