HOW DO WE DATE THIS WATCH?

From the serial number on the case back we can accurately date this watch to being made in May 1969.

CONDITION

In the 1960’s Seiko had two top end brands, Grand Seiko and King Seiko.  The King Seiko were aimed at a larger population than the Grand Seiko, and were priced a little less, but they were still very good watches.  First launched in 1961, the King Seiko range was recently relaunched (after a brief reappearance in 2000) and the range starts at £1,470 at time of press.

So what is a King Seiko Superior?  The standard watch was chronometer rated (not by COSC, but by Japan Chronometer Inspection Institute JCII), but they could do better than ‘just’ chronometer rated.  Japan’s Seiko also differentiated those watches that performed to the higher ‘AA’ accuracy grade which was aligned with the then Grand Seiko standard which since 1966 had been defined at -3 to +6 secs/day. Some examples met this higher ‘AA’ grade and were marked both on the dial and on the case back medallion with the words ‘Superior Chronometer’. All superior chronometer movements appear to have been manufactured in mid-1969.  The great advantage of having the word Superior on the case back shows that no one has fitted a Superior dial on a non superior watch – we all like these things to match.  On some watches with gold medallions on the case back there are also lost over time, but this one is fine.  The movement come out via the front of the case, and in order to regulate the watch there is a screw between the bottom lug.  This can be removed to access the fine regulation on the movement whilst it is cased – quite an elegant solution.  The leather strap is new, and could be swapped for a different colour if preferred.

This watch will be supplied with our branded presentation box and our Certificate of Authenticity.
