Here is a fabulous, all original King Seiko 56KS Hi-Beat Chronometer from 1970. The silver sunburst dial is in very fine condition, with steel Seiko and KS logos. It has railroad style steel bar hour markers with black contrast, double at 12 o’clock, and a painted minute track in between. There is a small mark at around the 14 minute marker. The tapered hands with black central contrast are in very fine condition. The steel framed window at 3 o’clock displays the quick-set date. This function should only be used with the hour hand at the bottom half of the dial.

The stainless steel bezel is in fine condition with some overall wear, perhaps most pronounced at around 7 o’clock. The stainless steel case with the original KS crown and heavy faceted lugs is in fine condition, showing some overall wear on both the case sides and at the lugs, most notably a scuff at the upper left case side. The stainless steel case back has a well preserved gold KS Chronometer medallion and is in very fine condition, with a few scratches and marks. The case does not appear to ever have been polished.

The watch comes on an after market leather strap of good quality with the original Seiko buckle in fine condition.

Inside the watch, Seiko’s high grade 5625A movement beats strongly and accurately to within about +-12 seconds per day. The watch was fully serviced in September 2026 and comes with a 12 month warranty on its proper mechanical functioning.

The KS and its “big brother” the Grand Seiko were made to show the world the prowess of Japanese watchmaking. They remain some of the most iconic and collectible vintage watches with an outstanding design and engineering quality. This 56KS Hi-Beat Chronometer is a great example of that and it is a fine watch for any occasion.

Our watches are delivered in a luxury wooden watch box, fully serviced with a 12 month warranty that covers the mechanical functioning of the watch under normal use. We offer 14 days full return rights and are very proud of our reputation for outstanding customer satisfaction.
