Just serviced, this Gen 1 Seiko was issued to the British armed forces.  Model reference 7A28-7120

HOW DO WE DATE THIS WATCH?

From the serial number on the case back we can accurately date this watch to being made in August 1984, and the issue number shows it was also issued in the same year.

CONDITION

The 7A28 movement (hence 7A28-7120) is a very high quality item.  It was the first quartz wristwatch to have analogue 1/10th seconds counter, it featured in watches worn by James Bond and the cast of Alien, and is so collectible that a forum dedicated just to watches has been set up.  One appeal is that they are fully serviceable, and we have just had this watch serviced.  That included new seals on the pushers, as they can become sticky otherwise.  This is known as the Gen 1, as the Gen 2 came later and had a different (cheaper) movement.  The only negative to report on this watch is the crown is not original, but a close likeness.  Being an issued watch there are signs on the case that it has had a life, but that is both to be expected and part of the appeal of military watches.  The NATO strap is new, and could be swapped for a different colour if preferred.

This watch will be supplied with our branded presentation box and our Certificate of Authenticity.
