It is called a "mystery dial watch" because the "hour" and "minute" hands appear to float. The case has a see-through back. "JUVENIA" was founded in 1860 and is a long-established Swiss luxury watch brand. Although it is not widely known in Japan, it is known as one of the oldest watchmakers in the world, and was highly regarded for its innovative design and technical skills, especially from the first half to the middle of the 20th century. Currently, it is valued in the antique market as a collector's item, and continues to operate as a luxury watch brand with small-scale production, headquartered in Switzerland. ●As it is a vintage watch from about 50 years ago, there is some wear and tear, but overall there is no major damage. Please check the photos. ●Before listing, I checked the operation and it is running well when the crown is turned. The daily difference was +38 seconds to +43 seconds when measured with a timegrapher in a flat position, which is sufficient accuracy for a vintage watch. (The daily difference may vary depending on posture changes, usage conditions, the remaining amount of the mainspring, and other factors, so please consider it as a reference.) ●There may be scratches and stains that cannot be fully captured in the photos. Also, the evaluation of the item is my subjective opinion, so there may be individual differences. Please refer to the description and photos and consider purchasing. ●Shipping will be done as quickly as possible and with careful packaging.
