Jewels
South Bend Watches of various numbers of jewels that have passed through our hands.
Jewels are used as supports at every point where wear or friction of the metal pinions in the watch might otherwise sooner disturb the adjustment.
In other words, the metal pinions run more perfectly, more smoothly and longer in jewel supports or sockets than in metal supports.
Therefore, the more Ruby and Sapphire jewels, the more expensive the watch and the better time keeper it should be, if otherwise perfectly made and adjusted.
