Up for sale is my Men's Ultra Rare Vintage Seiko SQ Octagon Shape Day/Date New Battery 7123-8520-P.  This watch cannot be found anywhere.  I've done loads of research on this piece and 2 things make it even more unique, the lion symbol at the top, and when you set the day/date, there is an option for Arabic letters to choose from as well as English and the standard calendar days.  The watch is running great.  Due to its age you can see signs of wear, but overall its a great looking watch.  Would make an excellent "everyday watch" or a collectors piece.
