Selling my 1st Gen Seiko Blue Sumo (SBDC003). The crystal was replaced by the previous owner with dommed sapphire. I added the blue Lumed ceramic insert from LCBI. The original insert is included, as well as a grey/blue insert (not ceramic). Also has a Miltat Oyster and the original bracelet. All links included for both. Please note that the previous owner indicated that the watch was pressure tested after the crystal swap. I have never submerged the watch. It has been keeping time with no issues, but I do not know if it’s ever had a service. It is in very good condition with very sharp lines (see pics).
