Seiko 7A28 Sports 100 Chronograph

Description:
Possibly sporting the finest quartz chronograph movement from Seiko, here is a beautiful condition 7A28 7049 Sports 100 dating from June 1983. This one has been fitted with what seems to be a new old stock bracelet and the watch case itself has been refinished at some point to a very high standard. These watches are becoming ever more collectible since it is some time since Seiko produced a fully jewelled quartz chrono movement.
