This is a working men's size Citizen C-mark hand-wound watch from the 1950s, with a new center second hand, Para-Shock, and Finox (check the position of the second hand in each image). The back cover is stamped "14K GOLD FILLED," meaning the body is 14-karat gold filled, not plated. This is a higher-grade model than the SS (stainless steel) model. The second hand is a new center second hand model, transitioned from the small second hand. "Para-Shock Finox" means it uses a shock-resistant device and a mainspring material that is difficult to break. It's about 70 years old, so the crystal (material unknown) has dirt and scratches, and the dial and body also have dirt and scratches, but it's an antique piece with an enjoyable antique feel. Please check the condition of the exterior in the images. The serial number is "1407084." The movement number is "75242." I received it from my watch-loving father a long time ago. I don't know the overhaul history. The timekeeping is reasonably accurate, about (plus or minus 3 minutes?) per 24 hours, but as it is an antique, its accuracy is not guaranteed. It is a movement without a hacking function. The belt is an aftermarket product, and its durability is unknown, so it is treated as an extra. The body size is approximately 3.4 cm at the center of the horizontal, including the crown, and the lug width is approximately 16.5 mm.
