Dial color change on PT Langematik Perpetual (310.025)...
Abe, you may know this. I found it interesting and surprising.
Technically, Lange never officially changed the dial color for this model. Your dial and Ray's dial are both "rhodium." But in fact they look very different. Back in 2013, I made some dial comparison photos, below, in different lighting conditions. The older dials were more matte, uniform, and to me had a slight pinkish hue. The newer dials were more of a metallic sliver, with greater contrast between the subdials and the main dial.
