The 7A28 is one of Seiko’s finest quartz movements, with a huge and dedicated fan base.  This 7A28-703A is nicknamed Pepsi due the red and blue bezel.


From the serial number on the case back we can accurately date this watch to being made in March 1983.


The Springbar blog did a very good article on the 7A28 series, all 42 versions including the James Bond one, the RAF model and the 7A28-703A.  That article can be found here.

This example is working perfectly.  The bracelet is a new aftermarket replacement, but has retained the original Seiko SQ clasp.  The hands are original, but the yellow chronograph hands are faded.  The dial is very good, as is the crystal.  The case has a few marks from being worn, as you would expect, but isn’t bad.  A new battery will be fitted before the watch is sent out.

This watch will be supplied with our Certificate of Authenticity.
