Bronze watches: extravagant – with a lively patina

Church bells, timpani, art objects, coins, medals, and molds for extruding pasta: many of these objects are made from bronze. Thanks to its appealingly archaic aura, this metal is even currently en vogue for use in watch cases. So-called marine or aluminum bronze is especially well suited for this application as it resists mechanical stress, saltwater, and corrosion thanks to an exterior film of aluminum. Due to these properties, the petrochemical industry and shipbuilders likewise rely on bronze. The owner of a bronze wristwatch must accept the fact that the surface of the watch’s case will acquire a patina, which gradually alters the timepiece’s appearance. This natural ageing process gives each bronze wristwatch a personal and individual note. Bronze contains copper, so a bronze wristwatch can leave green stains on its wearer’s skin. The industry counteracts this undesired effect by manufacturing case backs in titanium or steel. Incidentally: the original gleam of a bronze watch case can be restored relatively quickly by treating it with a suitable cleansing compound and a small brush.
