Restoring Casio TRW-20 Tachymeter Watch

Another great find on eBay. This Casio has tachymeter function which is used to calculate average speed. How useful it is to a normal human being in everyday situations is hard to say, but it looks cool!
This TRW-20 is mph version. It is identical to TWR-21 which is km/h version.
I did my best to make it look like original, unfortunately lettering was already halfway gone so I decided to remove it completely. You can see dust in between the crystal and face plate. I was afraid to take face plate out because that would probably damage it, so I decided to leave it. After I saw how disgusting it looks on the video I used vacuum cleaner to suck the dust out and that helped a bit. Thanks for watching!

This is what I had to do to my DB-112, except I polished with compound and a Dremel.

[@amineduskwalker7899]

I always hit the like button before the video starts playing because I'm always sure something cool is about to happen.

What is the battery model?

[@agentuk1]

Great video, just what I need while I try to restore the exact same watch. Can you tell me which strap you used?

[@blueXtwoplustwo]

Hi, I got one of this without strap, can you share with me what’s the lug size for this watch ? Thanks!

[@beberforumer9715]

Awesome restoration ! From what year is this watch? I had 2 casios and they both lasted 4 years only (with everyday use and never removing them even when sleeping or taking showers)

[@Techsas]

Thanks, I believe it's 1989

[@michaeljansen-tw1pk]

Great vid. What battery does the watch take ?

[@guppy7142]

Que pila lleva?

[@Kyrothan]

Does the watch have backlight? Or are these tachymeter watches without light?

[@Techsas]

No light

[@kobball2437]

Is there light on it?

[@ryoarts4347]

Maybe for you're next modifcation video you should mod the casio A1000D-7EF, which is a stainless steel modern casio that isnt a ghock

[@Techsas]

I would like to, but the price is a bit too high I think.

[@papadapa6212]

Do you do request for watches I wanna buy one

[@Techsas]

Sure, just shoot me an email at [e-mail]

[@user-is8lz6fj4l]

I can't imagine if this watch fusion with mudman G-9010 with LED indicator

Any alternatives to polywatch?

[@Techsas]

Toothpaste

[@guandasin3099]

@@Techsas will try, thanks man!

[@v1d300]

TIL : carpet buffing.

[@Techsas]

I learned that from a guy in the comment section. He also used toothpaste instead of polywatch.

[@v1d300]

@@Techsas I have plain white toothpaste to hide the scratches on plastic/synthetic faces but that polish doesn't last long. Haven't tried polywatch.
