Our Product Story
Exquisite, iridescent mother-of-pearl is composed of calcium carbonate. Its name refers to the inner layer of the mollusk where the material is found, often pearl oysters used for culturing pearls. The large shells from warm seas produce the thickest layers of mother of pearl.
In 1913, English metallurgist Harry Brearly, working on a project to improve rifle barrels, accidentally discovered that adding chromium to low carbon steel gives it stain resistance. In addition to iron, carbon, and chromium, modern stainless steel may also contain other elements that enhance the corrosion resistance of it. It is the addition of a minimum of 12% chromium to the steel that makes it resist rust, or stain 'less' than other types of steel. The chromium in the steel combines with oxygen in the atmosphere to form a thin, invisible layer of chrome-containing oxide, called the passive film. The sizes of chromium atoms and their oxides are similar, so they pack neatly together on the surface of the metal, forming a stable layer only a few atoms thick that is remarkable strong.
Quartz movement is where the movement power is provided by a miniature battery, eliminating the need to wind the watch. Quartz movements provide time measurement accurate to within a few seconds per year.
