Last week I bought a nice GW9010 from K42 (who is a scholar and a gentleman) that had the bezel ring painted black.
I thought to myself, why not go the whole way, and stealth the entire watch? Below are the results of my stealthing adventures, including a very good example of why keeping MEK in a plastic cup is a very bad idea.
Note: I did NOT have to take the module apart... it stayed sealed the whole time. I also boiled all the outer parts while I had them off, the buttons are nice and squishy now.
