Picked this up a while back and only just got round to doing a little work on it. Thought I'd post pictures as I went along.

The watch looked used but serviceable when I received it. It was however DOA although the auction indicated it just needed a battery change (pinch of salt etc). First job was to change the DW-9800 Wademan's two batteries.

692

First step was to remove strap and caseback. Solid pins, nice. The caseback screws showed signs of being opened before and weren't in super condition.

695

On getting it apart it didn't look good. Lots of fingerprints over the back of the module and rubber caseback seal thing. Also some of the module plastic was cracked around the battery clips. Oh dear.

694

On on regardless. Old batteries out.

693

Fortunately had the required SR927W / 399 in my spares box.

698

Fitted carefully without touching the module etc.

697

AC done with a staple, this step is often not required. Pretty easy though so why not.

696

Gave the module and caseback a clean with isopropyl to remove the worst of the dirt and corrosion.

701

Used a little silicon grease on the seal.

700

The moment of truth..... it lives. Quite glad to see that. Everything works as best I can tell, alarm, EL, thermometer and best of all compass. The only negative is the display dims slightly when changing modes etc. Seen this before which has been duff batteries, guess I can probably rule this out since their new. Pulled it apart again and cleaned everything again and ensured everything seated, still the same. Hey ho, at least it works!

699

Pulled the bezel off ready for a good clean. Which will be the next posting :D

Next step is the cleaning. Pop the band, bezel and module in a sink of hot soapy water.

929

930
931
Give it a good clean with a toothbrush and cotton bud. Lots of dirt to shift!

932

Leave it all out to try. Next step, painting :)

The next step is repainting the lettering. It's perhaps easier than it seems.

In this case the lettering to touch in is white. Casio actually seem to use a slightly off white colour but plain white is more straightforward. Following trying myself and reccomendation elsewhere I use Humbrol enamal model paint (think testors is the equivalent in the US / Canada) and a small model brush.

933

Prior to painting it's worth giving the areas to be painted a clean with isopropyl alcohol or similar to ensure the surface is really clean.

Next to paint. Simply paint over the lettering to be touched in.

934

936

Don't worry if it's not so neat, unless you've a super steady hand you'll not be able to keep it in the letters :)

Let it dry for an hour or two.

935

Then give it a wipe down. Again I used a cloth soaked in isopropyl.

You may need to do a couple of coats to ensure good coverage.

937

938

Results after one coat. As you can see coverage isn't perfect so applied a second coat below.

939

Pics to follow of complete item tomorrow :)

Hurry up! It's like watching paint dry ... :)

We seem to be getting a fair selection of "how to" threads. Worthwhile putting them in a separate section to make them easier to find?

After a second coat of paint on the 'wademan' text all that remains was to reassemble the watch.

And finally the wrist shot.

Happy enough with the final result. The main issue is the LCD isn't too clever, think the module must be on the way out. Suppose I could strip it down and give it a clean but I prefer to leave the sensor modules well alone (fropm bitter expereince !). Also where I've touched the text in the paint has stuck in some markings on the bezel. Overall however reckon it looks OK.

Now to collect the other four 'Men In Navy / Khaki' models :D

And here's what I started with.

Not picked the Wademan up for a little while, pulled it out the watch draw today to see this

Arse. Fingers crossed it's a duff battery although i'm pretty sure I installed new ones :(

Here's hoping. Fingers crossed on your behalf.

I have been thinking about the "paint in the text, wipe it off technique" as it is the next thing on my list of mods to try. Which solvents are safe with resin?

rutteger

If you've done the polarising mod painting some letters will be a breeze. I use isopropyl alcohol to remove the paint. Seems safe enough, used it on plenty of bezels over the years - I'm sure now someone will advise how bad it is ;). Currently use some 99.9% pure stuff from here (http://www.amazon.co.uk/ISOPROPANOL-Isopropyl-Alcohol-99-9%25-250ml/dp/B003D8QFQO/ref=sr_1_1?ie=UTF8&qid=1325028983&sr=8-1) but have used the stuff from the chemist too.

Finally had a quiet few minutes to take a look at this.

Back off, new batteries in. Nothing. Doh. Tested the old batteries fitted, supposedly new Sonys, both were flat. New cheapo eBay batteries showed 1.5v as expected.

Took batteries in and out a few times and tried AC, once or twice got something on the screen but the watch didn't 'start'.

As such decided to take it apart and clean the internals. Nothing ventured nothing gained...

1324

Came apart easily enough. Interestingly slightly different construction to other Gs I've taken apart. Normally the module sits in a rubber mount (which supposedly gives the shock resistance) and is decopuled from the case. Not here, the white battery section (bottom right in pic below) is clipped into the case. Once this is removed the whole lot falls out!

1323

Took it down to constituent parts. Cleaned with switch cleaner which is about the strongest stuff I have. Never 100% sure if it's a good idea using this on something as delicate as a module but I've never had issue with it in the past...

Reassembled is easily enough. First time it went back together worked first time. Hooray! Took the battery section off again to replace the alarm springs. Nothing. Doh. Then having taken a closer look at the module I realised I was using the wrong hole in the rear of the module for AC 1325 Got the right AC, module started up, all back together and working nicely. Phew. Display seems a little better than before but does seem to dim a little on occasion.


1322

Not sure if it really needed taking apart totally. Either way it works and that's enough for me :D

Good news!

As for contact cleaner it should be find for all electrical components and circuit boards which I believe are glass reinforced plastic. Won't swear to it but probably ok with other resin products like G-Shocks.

What would be good is for someone with some scrap watch platics to stick them in jars with various cleaners and see what degradation there may be after a few months. Maybe broken resin straps would be good test pieces - I can set up a couple of tests shortly.

Glad indeed - thought it was done.

Contact cleaner should indeed be good for PCBs although it is pretty strong stuff. When cleaning up a PCB on a plastic toy previously some split and melted the plastic pretty badly, as such I'd be wary of using on resin directly.

Be an interesting comparison to see what effect chemicals have on resin.

Where's the emoticon for speechlessness???

Your resto work, the pictorial chronology, and the end product all kick @$$...

Congrats - and thanks for the thread.

Thanks for your kind comments :D

Sadly not sure as this will end well. Took a look at the watch this evening and the display has gone very dim again :( May pull it apart one more time if only to check the drain on the batteries. However reckon I might have to write this one off - until I can find another good wademan module :cool:

ive heard you can use nail polish remover... what do you think? got a 9050 that looks like its colors are dulling out a little bit. someone also told me that nailpolish itself can be used to paint the watch? what do you think?

The problem with the wademan is the lcd as opposed to band and bezel.

Be interesting to see if nail polish remover would bring colour back to resin, give it a go ;) it'd clean it if nothjng else.

i was looking at your earlier restoration when i asked that question. i want to brighten up the letters on the CASE but i can take a little sarcasm. u said u used alcohol to remove the white piant on the wademan....i was asking you if remover can be a substitute??? you must think ive gone mad......:disillusionment:

Ahh, I see. Wasn't being sarcastic (can be much more sarcastic than that ;) ) but guessed we were talking at cross purposes.

To repaint the text I used model enamel paint (think testors is the big US brand?) But I've seen nail varnish used. Reckon the remover would work to remove the excess just fine. Give it a go!

One thing I have noted is the casio white text is actually off white, so if you redo any white on a bezel you'd be best doing the lot.

yes...i wet ahead and did it it looks just like yours when it was in repair...just having problems keeping it neat...my painting looks like a three year olds. for some reason all of the function indicators look perfect except the mode supposed ill try a toothpick or something thanks for the help

Good job having some looking good. The job on the Wademan isn't as neat as it looks, where the bezel is scratched the paint has run into it. Found it better to do a couple of thinner coats. Look forward to seeing the results :D
