☺ Overhauled and guaranteed to work ☺ ★★★ Genuine Product - Guaranteed Authentic ★★★ This item was purchased by my family's watch shop at a used goods market, which only those with a used goods dealer's 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. Therefore, you can be 100% assured of their authenticity. This is a vintage OMEGA Constellation, a ladies' watch. The Constellation, born as OMEGA's top-of-the-line series, is synonymous with high-precision watches and remains highly popular today. The model for sale is called the C-line, designed by Gerald Genta, who was hailed as the Picasso of watch design. This is a timeless vintage model loved across generations, and the price of those in good condition continues to rise. The item for sale is not only in beautiful condition but also comes with the original box and warranty (with the name of a jewelry store in Ginza), making it perfect for collectors. It is believed that only about 1 in 20-30 existing C-line Constellations have their original warranty, so if you've been looking for a good one, don't miss this opportunity. The body is made of stainless steel. The back cover features a relief of an observatory and stars. The silver dial has a delicate diagonal grid pattern, giving it a luxurious finish like fine linen fabric. There is a ★ mark at the 6 o'clock position. The words "Chronometer" on the dial are proof of a high-precision watch that has achieved excellent results in various observatory competitions. The movement is automatic winding, with a date display and a second hand. The 5-link Jubilee bracelet, comfortable to wear throughout the year, fits wrists up to approximately 17 cm. The watch's daily error, as measured by a timegrapher, is about +5 seconds, resulting in very high precision. The body's width is approximately 24 mm (excluding the crown). If you hold it in your hands, you will surely be amazed by its overwhelming beauty, which is rarely seen even in specialty shops. The image in the lower right of photo 4 was taken by a technician during the overhaul estimate. Unlike the simple structure of a hand-wound watch, automatic watches have a complex interplay of parts and gears related to the automatic winding mechanism, date display, and second hand. In my experience, watches that haven't been overhauled for many years rarely work properly. The serviced ones are reliable (^^)
