But that’s by aesthetic choice. There are still high-level finishes worthy of seeing here. The 18k gold rotor itself has 3 finishes applied, and has a nickel-anthracite-platinum-based coating to achieve the darker look. Striping, solarization, and other high-end finishes are applied throughout the dual-barrel movement as well. It sure isn’t a Lange, but it’s one the most impressive finishes you’ll ever see on a diver.
