I'd previously reviewed this watch here:
After ten minutes wear, I severely damaged the original green bezel insert. So I removed the bezel and found out about bezel springs and bearings, they immediately went AWOL. So I replaced one of them using a spring bar hack, dremel tool, magnifying visor, and a lot of grief. So now the bezel is bidirectional but at least it doesn't free spin.
As for a new insert, I looked around and saw the best deals on eBay. First, I bought a dark green ceramic insert from Zicorporate for $10. It's great looking and high quality, but it's a fraction of a millimeter too big in outside diameter, it seems ceramic runs a bit large. I tried grinding down the bottom, thought it might jerry rig, but it's impossible to grind ceramic without a diamond wheel, I didn't even scratch it with black carbide wet sandpaper.
Then I bought an aluminum insert from JacobJewelry for $10. I decided to be jazzy and went with a coke bottle insert. It had an adhesive backing and was easy to use, perfect fit. At first, I thought the insert was scratched, it looked poor. But then I realized it had a plastic film, so I carefully removed it with a fingernail, it wasn't scratched at all.
Too bad the picture isn't too good, but maybe people want to know what a coke bottle insert looks like on a green dial. I think it looks pretty good, sort of like Christmas.
P.S. I discovered that if you google "coke bottle insert" there's a lot of really strange results, stuff that has nothing to do with watches.
