Bronze, which currently is assigned a rather archaic historical significance, now appears to be rediscovered as a material in the watch area, for example in the manufacture of watch cases.

A consciously desired property of bronze is the discoloration; so a fabricated bronze object by and by, depending on use, takes an aging patina. Different factors play a role: Depending on body heat, humidity and air the material is getting darker by oxidation.

So each watch is by and by adapting an individual's appearance.
