Sooo, I decided to do a little experiment with my Ti/SS 192 rep. I had read about how mixing oxiclean and hot water and throwing a Ti watch in will oxidize the TI and give it a dark grey with blue look.
I wasn't sure about the water resistance of the 192, and how it would handle being submerged in a chemical bath, so I opened it up, and removed the Venus movement and dial from the case.
I put some oxiclean in one of my pots, stirred in some water, heated it on my stove on low heat, and tossed in the case and bracelet from the 192.
When it came out I really didn't like the blue-ish tint on the Ti parts of the watch, so very lightly wiped it down with a cape cod polishing cloth (barely touching it up), and the blue went away.
Lucky for me the Ti stayed a much darker grey than it originally was, creating a very strong contrast between the Ti and the SS parts of the watch, VERY COOL. Oh yeah, there's one other thing that happened, see if you can spot it. Here's the watch as it is now, re-assembled:
Yes, as you can see the tachymetre markings around the inner bezel came off. I didn't realize they were part of the case and not part of the dial, so when I put it in the chemical bath, the oxiclean stripped it right off. Now it's less accurate to the original, but the funny thing is that I like the new look much better, cleaner and less busy. I think the new overall look is pretty badass.
