BRAND: SEIKO MADE IN: Japan MODEL: Seiko 5 Sportsmatic 6619-8090 21J SERIAL #:6022733 MEASUREMENTS: CASE WIDTH: 36.5MM CASE WIDTH INC CROWN: 36.5MM LUG TO LUG (VERTICAL): 43MM INSIDE LUG: 19 CONDITION NOTES: This watch is in good condition for its age. Research places the production in October of 1966. The case shows some signs of wear from age. The inner dial has a nice patina to it, and the hands are in excellent condition. The date change works, by pushing the crown in to change the day, and setting the date from the first position, both function. The watch crystal shows signs of wear with light surface scratching, but is in good condition. The watch is fitted with a 20mm Black Leather band. The watch lugs are 19mm, so the 20mm band fills them out nicely. This watch looks cool and is currently running and keeping time. As with any vintage Seiko watch a full overhaul and cleaning should be done for daily wear.
