When you think of bronze, you probably assume it means third-best after gold and silver.

When used as a color for a case, bronze might be tops on the medal stand. Bronze is made from copper and tin. Unlike other metals, it won’t corrode and won’t be affected by saltwater, making it a unique element for a watch. (The Watch Doctor still recommends keeping your watch dry by not showering or swimming with it on.)

Here are a few examples of watches with bronze cases.
