BRAND: SEIKO MADE IN: Japan MODEL: Seiko Crown Diashock 21J SERIAL #:NA MEASUREMENTS: CASE WIDTH: 36.5MM CASE WIDTH INC CROWN: 38.9 LUG TO LUG (VERTICAL): 43.5MM INSIDE LUG: 19 CONDITION NOTES: This watch is in good condition for its age. Research places the production in the early 60's. The case shows some signs of wear, but the overall stainless mirror finish is still very nice. The inner dial is showing signs of age and damage, but is still very nice, and the hands are in good condition (please see photos) The watch crystal is in excellent condition, with only a minor scuff at the top 12 position, it is hardly noticeable. The watch is fitted with an 20mm Black Leather band (lugs are 19mm, so 20mm fills them out nicely). This watch looks great and runs well, currently running between -3~-5s/d. As with any vintage watch a full overhaul and cleaning should be done for daily wear.
