Option #3 it is!!! Today at lunch I drove down to ofrei... Yes I am lucky, their warehouse is about a 10 minute drive from my work, so no shipping! The place is a sight to see. I could have never imagined so many watch parts, tools, and jewelry in packed into one big room. People running around everywhere filling orders, it was crazy.
In any case, I picked up another bezel insert from them in the interest of education. Here's what it looks like, this is not glued in, just balancing on top. Pearl seems good to me, and it fits (with a little bit of work... look below)
It was a little too large when I got it, so I had to grind the outer edge a bit... My method (flame away if you feel the need... I'm a noob) was to attach the bezel to the end of my drill with a little bit of silly putty. Then I used a diamond stone (used for deburring ski edges) to take it down ever so slightly while the drill was running. This takes forever, but leaves a edge with no burrs.
Here's a comparison of the 3... all pics are in this order...
1. $15 Ebay Insert
2. Original from Trusty
3. Insert from Ofrei ($35)
Notice the difference in the shape of the 4... I've seen both on Subs (I think 2006 model has the 3 sided one? Maybe you guys know)
And to finish it off... a gratuitous lume shot Note: Give the credit to the camera, not necessarily the lume
