The Bronze Field Guide

Learn About Bronze Watches

Bronze is the one case material you buy for how it changes. A copper alloy tarnishes into a living patina, unique to the wearer, which is the whole point. But bronze is a family of alloys, not one metal, and how a watch is built decides whether that copper ever touches your skin. These guides explain the material language used across the Bronze Field Guide.
