Here are photos of the test installation of the plates.
1.) The reduced height with the faux screw heads allows the CdG dial plate to slide in as replacement for the rep plate without widening the distance between movement and top of dial. That means all small chrono hands have sufficient distance from the dial to operate smoothly.
2.) The contrast between the smoothly polished screw heads and center gear with the CdG surface adds to the presentation quite a lot. If you are installing these plates, makes sure to clean the screws and gear with spirits and a dust-free clothe to get the maximum shine. The screws and gear are pre-polished by me to a high gloss, but the plates might pick up dust and dirt while shipping.
Everything seems perfect for an uncomplicated installation.
