※ Mint condition, appearing to be a new, unused item. ※ Market price at antique shops is over 70,000 yen. ※ The cosmetic box is for photography purposes and is not included. ● Included: Genuine buckle (bonus) ● 1970s Japanese-made, first double-sided skeleton, automatic wristwatch. ● New, unused aftermarket rubber strap attached (bonus). ● Purchased in "near-new" condition with accuracy within 1 minute per day, unknown OH history, and kept in a collection. (Stored without use after purchase due to its excellent condition) ● Currently running and keeping good time (no warranty). ● The rare blacky case, bezel, crown, and movement are a perfect match in gold, giving it a very luxurious feel. ● The red second hand with a dot at the tip is an exquisite accent color, giving it a Showa retro atmosphere. 【What is a Blacky Case (Special Light Alloy)?】 • Special processing that is resistant to scratches (black Hardermite treatment) • Lighter in weight and superior in strength compared to stainless steel. • At the time, double-sided skeleton wristwatches made of stainless steel were also sold, but this blacky case was produced in smaller numbers and was more expensive. ● A must-have for Japanese antique watch enthusiasts who want to endlessly watch the movement of gears and the balance wheel, unlike Seiko, Orient, and Ricoh. ● Although there may be slight age-related deterioration such as minor scratches from long-term storage, as you can see from the photos, there are no scratches on the glass surface, and from a layman's perspective, there appears to be no rust or discoloration within the visible range, making it very clean for something approximately 50 years old. ● The crown is not stuck, and winding is smooth. ● No paint peeling on the blacky case. ● Luminous paint is still intact. Although it is in near-new condition and keeps good time (no warranty), it is a vintage, unserviced mechanical wristwatch, so please have it overhauled if you intend to use it. ※ This is not a brand new, unused item. Also listing or planning to list Ricoh, Seiko, Citizen, Orient, Technos, Bulova, and Edox.
