This time is "hero" watch which saves g-shock production line from extinction.
Looking good with minor scratches on mineral glass, comes with discolored bezel and original replacement band.

Perform brief cleaning with 70% alcohol. Rust is observable on bezel screws end, and I dare not attempt to remove by force, sometimes it is good to keep it the way it looks, don't you agree?

I replace all rubber seals from a DW5600E. These pushbuttons from DW-5200 can be inter-switched between DW5600E, except for the "adjust" pushbutton which is smaller than DW5600E.

Then I submerge in water to see if waterproof is still applicable to the watch. 10 minutes passed, no sign of water seen in the watch.

Finally, DW-5200 in its brazillian bezel & band look:

There is one more thing, I use sand papers try to remove scratches from the mineral glass, and results are terrible--> even more scratches.
Can somebody please share what type of abrasives are suitable to remove scratches from this watch? Thank you.

Sandpaper won't polish the crystal, you will need to use cerium oxide powder mixed with water to polish the crystal to crystal-clear. Use sandpaper to pile down crystal until scratches disappear, make sure you use very fine sandpaper right before you polish with cerium. Diamond paste works too but a lot more expensive than cerium oxide.

People are saying "sandpaper" but I think it's better to say "micromesh"... which refers to the much finer abrasion types and doesn't involve "sand". ;-)

Yeah, to get rid of those deeper scratches you need to shear off a fine layer of the crystal... so you start with one degree of abrasive material and slowly work your way down to the cerium oxide paste.

My gratitude for your detailed information!

i'm using cerium oxide too, and its definitely working, but its a lot of work. don't expect for it to work fast.

it's taking me days to fix my hero and an old gold speed, but the scratches are slowly disappearing
I have spent 4 hours in refurbishing this watch. No rush, just watching it disappear slowly is a good enough reason for me to conduct polishing.

Thanks. I would polish it circular iteratively.
