I have been interested in this watch for a while. The DW-8200BK is a watch that has developed a kind of mythical status in the world of G-shocks, for reasons I never quite understood. I liked it, but I didn't LOVE it like some collectors. I had a "7th Frogman" DW-8201NT which is similar in the sense that it is a positive display LCD with a reverse-looking backlight. When the backlight is pressed, the numbers light up and the backgroud remains fairly dark, much like a backlight on a traditional negative display. I liked the DW-8201NT, but I always liked this one, the Real Black frogman, as well. Problem was--the prices were always outside my budget. These were selling for $900 regularly. Now that is has been some time, and newer frogs have come out (there are like 100 versions of the Frogman released so far) the prices on some of these older models are starting to fall. There is a rumor that this has a sapphire crystal (it does not) or that it was for sale by invitation only (I am pretty sure this is not true either)
I picked this up off ebay pretty cheap ($247 plus shipping). I have never seen one sell for so little. It is not perfect. For one thing, the bezel was fake (the seller did announce this by saying it was not original). It doesn't fit properly, is made of inferior resin, and has screws that are clearly not titanium (they have corroded). On top of that, there is some hazing under the crystal, a scratch on the caseback, the band needs replacing, and (this did not show in the photo) some minor scratches on the glass.
I got the watch yesterday night, at the same time as a new set of resin from Japan (bought off Rakuten)
First thing I did was replace the battery and grease the gasket. I removed the module and attempted to remove the dial but found that it was adhered to the case (I guess this is how these old 8200's are designed. So I was not able to remove all the haze on the dial. Here is the work I did last night and this morning:
1.) Open watch. Replace battery. Perform reset.
2.) Grease gasket
3.) Examine dial. Find that it cannot be removed.
4.) Clean accessible areas of the underside of crystal with a Q-tip
5.) Create a thin strip of "floss" out of an eyeglass cleaning cloth, soak in alcohol, and "floss" the top of the bar on the dial to remove the smudge that discolors half of it.
6.) Spray inside of watch with compressed air.
7.) Reinstall module, gasket, other parts, and close watch.
8.) Seal tightly, and wash outside of watch thoroughly with toothbrush and soap
9.) Place 2000 grit sandpaper on table, place watch on top, and sand caseback until scratch is gone.
10.) Rough up caseback with kitchen sponge rough side to restore matte look
11.) Rub caseback with Scratch X, toothpaste, kitchen sponge, and toothpaste again until desired look is achieved
12.) Polish scratches out of crystal (this part takes the longest by far. Hours. All the other steps combined take less time than this
13.) Clean watch with toothbrush and warm soapy water
14.) Clean small spaces of residual cerium oxide with dental tools and compressed air blaster.
15.) Install new resin, screws, and springbars
That's it! Here are the finished photos. Note, I could not remove all the haze from under the crystal because I could not take off the dial. I did not want to risk damaging the dial because this is the only Frogman that uses this exact dial and it would be near impossible to replace.
The display looks orange in some light, and pink in other light.
