The 7A28 series was introduced by Seiko in the early 1980s and the technology employed was pioneering at the time. This series was the first quartz chronograph movement produced with an analogue display and has really earnt its place in horological history. Not only is the watch capable of measuring 1/10ths of seconds (watching this is mesmerising!) the tenths hand hits 0 at the exact same moment as the second hand hits each second- a true indication of the time, thought and effort put in by Seiko.
This particular model was commissioned by the MOD to be issued to Royal Air Force pilots in the 1980s and early 1990s. MOD issue numbers along with the broad arrow symbol are present on the case back. It is said that only around 10,000 of these watches were made throughout the issue period, and were only available to RAF pilots.
The water resistance has not been checked so cannot be guaranteed.
