☆ KS Top-of-the-Line Chronometer Special This is a "52 series King Seiko Chronometer" model. The movement is the highly accurate automatic winding caliber [5245A] (Hi-Beat / 28,800 vibrations per hour), which Seiko boasted at the time. It is a capable machine that has accuracy that is still valid today. ★ Currently running, with an error of about 5 seconds per day. ★ The calendar switching is faulty. I was told that it could be repaired at a watch store. ※ The 56 series is a mass-produced, popular item as KS. ※ The 52 series Special is a "culmination" of sorts, with a focus on mechanism and finish. ※ This model is particularly popular for its rare "linen gray dial (charcoal gray)", and has high value among vintage King Seikos.
