This is easily one of the coolest sunburst dials I’ve seen on a vintage Seiko. It completely changes from navy to light blue under the right lightning. Plus, the angular case measures a tasteful 37 mm, which is perfect for any wrist. Serial dates it to December 1978. **Condition:** Very good, minor markings on the case and crystal. See detailed photos for full condition and clarity.  **Case Size:** 37 x 41.4mm case with a thickness of 11.1mm and 19mm lug width. **Movement:** Seiko 6309, automatic with 17 jewels, 21,600 bph, a 47-hour power reserve, and quickset day/date. Service history is unknown, but everything is working as it should. **Other information:** * Aftermarket leather strap. **Price:** Asking $150. Please add $20 for worldwide shipping. Payment methods include Wise, ACH transfer, Revolut, Bitcoin (On-Chain or Lightning), or PayPal G&S for buyers with solid references. Add +6% for currency conversion fees on the latter. I’m located in Portugal, but worldwide shipping isn’t an issue.  Established seller with over 220 transactions – buy with confidence!
