Breguet

Is the painted guilloche gilt-edge, too? ...  

Very nice details, a joy to admire!

Great shot !

They call it guilloche a main because it is done by hand-controlled machines. If you aren’t very, very careful with the pressure, the cutter will dig into the surface and ruin the pattern Roger Smith did a short series on guilloche on YouTube that’s great... 

Maybe I'm missing something, but what has flinquée enamel got to do with it? Breguet is known for their pretty excellent output of guilloché dials.

Please notice the parts of dial which painted with blue and without silver powdering.
