This date only King Quartz is different to most of the Seiko KQ range of the time, and has the original bracelet too.  Model reference 5855-8000 or QHC020.

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 1977.  At the time it cost ¥51,000, which was more than double the cost of a Seiko automatic chronograph, or their Bell-Matic alarm watch.

CONDITION

Seiko were the first to launch a quartz regulated watch, which they did on Christmas day 1969, and they changed the watch industry and what customers wanted.  Almost every brand followed suit, recognising that mechanical watches were expensive to make and maintain next to their quartz rivals, and could not be as accurate either.  But quartz watches became cheap and disposable, and this gave them a bad name in the 1980s.  This King Quartz though is from a different era, where making the best quartz movements rather than the cheapest was still the aim.  The Grand Quartz models were the most accurate, but the King Quartz were not shabby either – this watch is running at +0.33 of a second per day fast now.  We will install a brand new battery before sending the watch out to the new owner.  The dial has an almost linen pattern to it, but it is a little too geometric to be linen.  There are a couple of small marks on the dial, but the glass is faultless.  The original bracelet, reference XOB040, is full length and has a sliding clasp, making adjustment easy without the need for special tools.  The bracelet has been cleaned in our ultrasonic bath.  The watch is signed on the dial, case, movement, crown and clasp.

This watch will be supplied with our branded reusable presentation travel case and our Certificate of Authenticity.
