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.

This particular watch is in good cosmetic condition. Minor scratches and scuffs can be seen on the case, bezel, and crystal. The gold plating is in overall good condition. There are a couple of spots on the bezel wear the plating is starting to wear away. The mainspring in this watch is broken. However, the watch still runs and winds and will need a new mainspring to achieve full performance. The power reserve is less than 12 hours in its current state.
