Seiko King Quartz Hidden Function

The Seiko 08 series was introduced towards the end of 1974 and was used in QT, QZ and King Quartz branded watches. The QT series used the 0822/23; the QZ, the 0841/42/43 and the highest-end King Quartz, the 0852/53. Rather than simply contributing a redundant range of Daini quartz models for the sake of it, these watches were pitched at a price point 20 to 30% lower than the Suwa-produced 38-series equivalents. The King Quartz 0853-8025 described here dates from December 1976 and features a hidden feature that I only appreciated was there once the watch was up and running again after service. Watch the video to find out what this hidden feature is. The full story of the restoration can be found in a post on my blog here: https://adventuresinamateurwatchfettl...
