The 45KS was introduced in 1968 with the brand knew 4500 caliber designed by Dani Seikosha. It featured an angular case with sharp edges with a reference number 45-7000. The 4500 movement was designed as a hi-beat successor to the 4400 series of movements. It is a manual wind caliber that ticks at 36,000 beats per hour, or 10 times per second. In 1971, a new case design was released, 45-7010. It featured a more conventional oval shaped case with a brushed finish but houses the same great 4500 series movement. The 45KS was the last of the 36,000 hi-beat movements from Daini and the last hand-built King Seiko. \- **Ref No. :** 4502-7001 \- **Serial No./Year:** 373227-/-1973 \- **Case:**     37.25mm diameter, 18mm lug width, 9.65mm thickness, 42.2mm Lug-to-lug.     Stainless Steel \- **Crystal:** Hardlex \- **Movement & Accuracy:**      Caliber: Dani-Seikosha Cal. 4502 Manual Wind     Complications: Central Seconds, Quickset Date     Measured Accuracy: +0 sec/day.     Amplitude: 159°     Beat Rate: 36,000 A/h \- **Band:** Replacement Stainless Steel Bracelet.
