Selling my Seiko SBDC003 blue Sumo which is a cool 17 years old. A very early version made in June 2008 and purchased by it's original owner in September of that year. I am the second owner and have had it about 3 years.  Original owner had a sapphire crystal installed by his watch maker, OEM crystal unmarked and included just in case you want to return it to stock.  3 extra links were purchased, 2 fitted to the bracelet and 1 spare, it should fit in excess of an 8.5" wrist.  For it's age this watch is in very good condition with a little nick in the bezel at the 4 minute mark, not too noticeable on the wrist.  6r15 movement keeping time well within spec although service history is unknown. I know from talking with the previous owner he looked after this watch I think he may have had it regulated.  Original yellow Prospex box tags and booklets unfortunately no black pillow. Asking price is $425 PayPal or we can talk other options, you pay fees I pay insured shipping. This is a fair price for this watch considering the sapphire and extra links. Price is firm for now and I will list on the bay if it doesn't sell.
