Question on Rolex Balance Wheel
As my first post, I'd like to start by saying... wow... what a nice community. I found this forum about a week ago and it just seems so lively, I had to join. :)
As for my question, I have some Rolex Balance Wheels for the 1520 movement, and was a little confused... why is it that some of the hairsprings are silver, while others are blue/black? I've been trying to figure this out but my research has led me nowhere... any ideas? |
