Some of the most popular 1980’s watches today are the Seiko 7A series, and the 7A48 was the most complex of them all.


From the serial number on the case back we can accurately date this watch to being made in July 1985.


So why are the Seiko 7A28/38 and 7A48 models so sought after?  They can be accurately dated to a year (and month) of production for a start.  They are larger than most quartz watches of the 1980’s, so are more wearable today.  The 15 jewel movement can be completely stripped and serviced, unlike some quartz watches.  The cases are usually made of stainless steel, as with this model.  And this movement was also a horological first – it was the first time a 1/10th second chronograph was made with a quartz movement, ever.

This example has been used frequently, and the case and bracelet do have various small scratches and scuffs.  We have cleaned the large, original bracelet in our ultrasonic bath and replaced the crystal.  All the functions work as they should, including the quick set date and moonphase (this site will be able to tell you the exact phase of the moon wherever you are).  The pushers have been cleaned, but still require a strong press to activate everything.  The watch will be fitted with a new battery before being sent out – the last 7A48 we had was in better condition but sold for a lot more money very quickly.

This watch will be supplied with our Certificate of Authenticity.
