Designer Optics is an Official Seiko retailer and has a wonderful customer support team willing to answer all questions. Combine that with great prices and you get an online shopping experience that you actually want to tell people about. I'll be checking here first for my future Seiko purchases. Thanks a lot Designer Optics! Oh and the Sprk17 55th anniversary Seiko 5 is a solid vintage homage to their 1968 model and feels great on the wrist.
