The Aquatimer Charles Darwin Edition was one in a series of bronze-cased watches I cycled through a few years ago, when I was fascinated by the material. The watch wore quite well for its great size (44 mm x 16-17 mm) and the flyback chrono operated nicely. However, the rubber coating on the chronograph pushers was not durable, and its deterioration was the eventual reason for my letting the watch go. Interestingly enough, I traded away the last of my bronze watches a while back, and have not yet been tempted to try another.
