Why is my bronze watch changing color?

Bronze is a living material that naturally changes appearance over time.

As the metal is exposed to air, moisture, skin chemistry, and environmental conditions, it develops a surface oxidation known as patina. This process may cause the bronze to become darker, lighter, or develop unique color variations.

These changes are a normal characteristic of bronze and are often appreciated by enthusiasts because they give each watch a unique appearance that reflects its individual history and use.

Patina does not affect the structural integrity or performance of the watch and should not be considered a defect.
