I run a watch page on Facebook and one of my followers/readers has asked a really interesting question regarding a post on the Breguet Classique 5157 ...
The dial is made from solid yellow gold, but is then silver plated. I'm guessing it's silver plated mainly for the colour. However why not start with a silver dial, or a white gold dial? Is gold easier to engine turn to create the guilloche dial?
Any ideas? :)
