Casio Shadow SHW-100

As I find more and more watches, it has become apparent that the Casio brand has produced so many different lines/ranges of watches, and that many of them were so obscure that their history is a mystery.

Today's watch is a Casio model from a range called Shadow. I've not been able to find anything about the range itself though, as the only other models I find online are purely watches for sale. What i know is that there were several (at least 3) different models in the Shadow range, and all of them had a dial as the primary time display.

This model is a 3 hand dial design with a Casio 1307 quartz module. The styling is very industrial with lots of exposed bolts (for cosmetic effect) and protruding plastic 'grills'. It is an Illuminator model, which suggests a market outside of Japan as those are normally called Foxfire. When pressing the light, the word Shadow appears right across the dial, written in a very stylized font. The dial also has the Shadow name written normally near the bottom along with the Illuminator name and that it is 10 bar water resistant (with the use of bar maybe suggesting an American market). The back has the same information, as well as saying it has a Korean module and was cased in Malaysia.

From what I've read, the Korean models began in the 80s, and the Malaysian Casio's more recently again, so the only thing I can find about the date is that it is likely from the 90s at the earliest, but is not a current range.
