vintage Seiko 5 automatic. However, there is a notable discrepancy between the dial and the caseback that is common with vintage Seikos. While you requested details for a 7009-3040, the caseback in your second photo clearly shows the reference 6309-8500. The dial itself features the "7009" movement marking (visible in small text at the 6 o'clock position). This suggests the watch may be a "parts" or "Franken" watch where a 7009 movement and dial have been placed into a 6309-8500 case. Below are the technical details for the components shown: Technical Specifications (Movement & Case) Movement (Dial/Internal): Seiko Caliber 7009A Type: Mechanical Automatic (Self-winding) Jewels: 17 Jewels Beat Rate: 21,600 vibrations per hour Functions: Hours, minutes, central seconds, day, and date. Quickset: The date is changed by pulling the crown to the first click. The day is uniquely changed by pushing the crown in toward the case. Case (Backplate): Seiko 7009-3040 Material: Stainless Steel Design: Rectangular/Tonneau-style integrated lug case. Crystal: Hardlex (Mineral glass) Dimensions: Approximately 37mm to 38mm in diameter. Key Identification Features The Dial: This specific dial features a "tuxedo" or two-tone silver/grey finish with a circular inner ring. It has applied gold-tone indices and hands, which contrast with the stainless steel case. The Day/Date: Displays the day in two languages (likely English and Spanish/Roman, indicated by "DOM" for Sunday). The Bracelet: It is fitted with a stainless steel "Jubilee" style folded-link bracelet, which was a standard pairing for the Seiko 5 line during the late 1970s and 1980s. Manufacturing Date: Based on the serial number 587814 on the caseback: The first digit (0) indicates the year (1980). This case was manufactured in August 1980. this item have ship with tracking cost 20 usd or ups 50 usd Condition Notes The "7009" movement was the successor to the "6309." While they are both robust "workhorse" movements, they are not always a factory-standard match for this specific case reference. This setup is very common in the vintage market, especially for watches sourced from regional distributors in the 80s and 90s.
