seiko crystal

  1. 7s26 dress crystal replacement

    I have a 7s26-0500 case laying around and i am going to put a 6r15 dial on it, without the day function. Therefore i am looking for a replacement crystal with magnification. The original seiko glass has the code 290P05HN03. Is it safe to assume that the width is 29.0mm and the height 0.5mm...
