Well, I had received a beautiful, pristine california dial 3646 from Neil and decided to experiment on some vintagizing ideas. Some of you might recognize it as one I sold to John a few days ago. I sold it to fund other projects. But, I just wanted to share some of what I did and some pics. First, I removed the crystal, stem, strap, and caseback and gave the entire case a medium coarse satin finish with sponge-type wood finishing pads - I started with medium grit and went to fine grit. I did the same to the end of the crown and to the crystal bezel ring. I rubbed the crystal lightly with a pad, then repolished using brasso to give it a worn, but polished look.
With the crystal already removed, I went to work on the dial and hands. I used one of my kid's black charcoal pencils to color the indices and hands. I also dabbed the indices with a gummy eraser to balance between the original color and the charcoal color. This went much better than anticipated, and it was very easy - no messy paints, no dipping in expresso or tea. Once I got the indices to a desired color, I took a pad and scoured the entire dial in a circular motion to give it an even faded look. Looking back, I think maybe a dark brown or dark orange color would've worked nicely also.
Also, I wiped the metal frame of the hands with a pad to give some wear to the edges, so in certain light a hint of metal would show through. Finally, I reinstalled the hands and put the case back together. I vintagized the strap using a scouring tip on my dremel. Then, I sold it to fund another project (6152!!). Here's the pics:
