I’m the original owner of this first gen Sumo. Ordered it from Japan 10+ years ago and dropped it the first time I wore it out “my bachelor party” the hardlex crystal got biffed on the pavement and I didn’t wear it much after that. I bought a double domed sapphire crystal for it but I didn’t get around to having it installed till a couple weeks ago. The watch now has a freshly installed double domed sapphire crystal on it. I also had the shop do a pressure test on it at that time. The case and bezel are in very nice condition with a few scratches on the underside of lugs from strap changes etc. The original bracelet is complete and unworn. Watch will come on a lightly used crafterblue / black rubber dive strap. I can’t make any comments on its time keeping since I haven’t worn it much. I would assume it needs regulating at minimum. It’s a nice example of a pre logo Sumo, I tried to bond with it but honestly my collection has moved towards smaller wearing pieces so It’s time for this to find a new home. I’m new to selling on Reddit but have a long history and good reputation on watchuseek “over a decade” and can confirm identity there. I’m asking $425 full kit, to/from conusa. I accept PayPal or Venmo. Thanks for looking. Timestamp and more pics here: https://imgur.com/a/GyaPbjV
