Watch Materials

Traditionally, gold has been the standard material used for watches, but over the years styles and looks have changed. Materials widely used in the automotive, medical, and aerospace industries have permeated horology, inspiring watchmakers to experiment with new lightweight elements and fusions such as:

Stainless Steel
Ceramic
Titanium
Carbon Fiber
Physical Vapor Deposition (PVD)
Diamond-like Carbon (DLC)
Gold
Rubber/Silicone

Gold watches

Gold

A metal in which fineness (the percentage of pure gold versus the percentage of base metals) is expressed in karats. 18 karat gold (75 percent pure gold) is standard for watch cases and high grade jewelry in white, yellow, rose and red gold. This is obtained by adjusting the proportions of copper and silver in the 25% of the alloy not consisting of gold.

Yellow Gold

Pure gold alloyed with other metals

White Gold

Pure gold alloyed with silver, palladium, or rhodium.

Rose Gold

Pure gold alloyed with percentages of copper. The more copper added, the darker the hue. A small percentage of silver or zinc can be added for a desired tone.

Rubber Silicone watches

Rubber/Silicone

A rubber-like material comprised of silicon, carbon, hydrogen, and oxygen

Traits

  • Heat and cold resistant
  • Good weatherability
  • Water repellent
  • Pleasant to the touch with a high-grade feel

Other uses

Medical applications, consumer electronics, office automation, automobiles, electrical wiring, food
