[Categories] Jewels [Answer] The “jewels” used in wristwatches are not genuine precious stones. Designed to reduce friction as well as mechanical wear and tear, they are made from industrial standard rubies and are used mainly for bearings, levers and detents as well as for the pallet stones of the escapement. Although natural rubies were used in the past, synthetic rubies with practically identical properties and higher homogeneity are used today. [Question] 
What “jewels” does IWC Schaffhausen use in the manufacture of its movements?
