A rare opportunity to acquire one of the most sought-after King Seiko references: the **45-7000 Hi-Beat**, powered by the legendary **Cal. 4520A** hand-wound movement from Daini Seikosha. A pure execution of **Taro Tanaka’s “Grammar of Design,”** this model is admired for its architectural case geometry, razor-sharp angles, and refined finishing. **Condition Highlights** **Case: Factory-sharp**, completely **unpolished**, with crisp case lines and original geometry preserved. The chamfers and planes are still clean and well-defined—something rarely seen today. **Dial:** Fully **original** and untouched. No retouching, stains, or dial degradation—honest and elegant. **Hands & Indices:** Original dauphine hands and applied markers remain **clean, reflective, and free of corrosion**. **Caseback Medallion:** The **KS gold medallion is exceptionally well-preserved**—**sharp, clean, and intact**, with **the original protective lacquer film still visible**. This is extremely rare; most examples show worn or faded medallions. **Movement:** Powered by the **Hi-Beat 36,000 bph Cal. 4520A**, celebrated for accuracy and refined engineering. **Overall condition:** The watch shows **very minimal usage,** suggesting it spent most of its life protected rather than worn**.** As with any vintage piece that has not been used regularly, a **routine movement service is recommended** to ensure optimal long-term performance. **Accessories:** Comes with its **original Seiko alligator strap** and **original Seiko presentation box.** **Collector’s Note:** Most surviving 45-7000 examples show polishing, dial flaws, or worn medallions. This example stands out as **exceptionally honest and original**, with **case geometry, dial condition, and medallion preservation** that put it in the **top tier** of available specimens. **Sale Price:** $1050, including insured shipping within the US (PayPal F&F preferred; G&S accepted if buyer covers fees) **Other Info:** I am a new US seller here but have a **13-year eBay account with** **100% positive feedback**. **Timestamp**: Included in the last photo.
