I have a very late Gen 1(2014, Gen2 was 2015) Japanese Sumo for sale, recently serviced.
The complete service thread is here, please read through it and contact me for any questions. I just realized this is the original SBDC reference.

If you don't like the Prospex X dials, this is the one for you. Condition it's well worn which you can see from the pics, but no serious damage.
45x13.8x52mm L2L
20mm lugs
WR get it checked properly before dunking!!
This is not a small watch, and at 176g currently sized you could do some damage if you swung it.
Bezel insert in surprisingly good condition, feels good to turn. Bracelet a few links shy, probably around 6.75" (6 removable links). Takes Seiko fat bars and a 20mm strap.
Used prices around $600
I'm asking $500 plus shipping , offers welcome.
