☺ Overhauled and guaranteed to work ☺ ★★★ Genuine Product Guarantee ★★★ This item was purchased by my family's watch shop at a used goods market that only those with a used goods license can enter. I personally purchased and am now selling it. All watches have been overhauled and maintained, with every detail of the internal mechanisms checked, so you can be 100% assured of their authenticity. This is a high-end model of the Omega De Ville Sapphette, popular among Omega's antique watches, featuring an 18KWG/750 solid gold specification. The solid gold model provides a pleasant sense of weight when held in your hand, and you'll feel satisfied every time you wear it. Also, this model has a slightly larger face diameter compared to those with standard cut glass, making the time easier to read and offering an appealing size. The body is made of K18 white gold. The Swiss hallmark, indicating the purity of gold, is engraved on the inside of the back cover. The movement is manual winding. The dial is silver. Since you look at the watch dial many times a day, any noticeable dirt or aging will inevitably bother you later. You won't regret choosing one with a clean dial from the start. A black crocodile leather strap has been selected. The buckle is a genuine Omega product. The diameter of the body is approximately 19.5 mm. The watch's daily error is around +5 seconds, as measured by a timegrapher, resulting in high precision, so you probably won't notice any error during actual use. It maintains the best condition for a vintage wristwatch, and you'll surely be surprised by its overwhelming beauty, which is rarely seen even in specialty shops. The image in the lower right of photo 4 is a picture taken by a technician before overhauling this watch. Overhauling involves disassembling the movement to a certain extent to check the condition of each part, then completely disassembling it, and manually pre-cleaning each part to remove oxidized/deteriorated oil and fine debris. After that, it undergoes main washing and drying in an automatic washing machine. The movement is assembled while using different types of oil on the cleaned parts. After assembly, it is placed on a dedicated tester for several days to adjust the accuracy. Mechanical watches that run on a mainspring are designed to be overhauled periodically.
