PRE-OWNED: Seiko Sumo SBDC031 6R15-00G0 FOR REPAIR/SERVICING (READ CAREFULLY)
Second generation Sumo with Seiko 6R15 automatic movement. Plenty of signs of wear: small scratches all over the watch, a very scratched crystal, but no major dents. Sold for repair without warranty or return option.
All functions work and the watch runs, but as the Timegrapher photo indicates, amplitude is way low, beat error significant and readings all over the place. The watch has been de-magnetized, but obviously the movement needs proper cleaning and new lubrication. For replacement crystal, I warmly recommend Seikomods.com Sumo sapphire crystals.
