Movement Ring

5020b

This antique movement ring features genuine rubies.  Why waste rubies inside a watch?  They are used as bearings for moving parts due to the low friction and good wear characteristics. Low friction equates to increased accuracy in watch movements, so better watches use jewel bearings, even to this day.  Consider yourself schooled!  Antique Silver adjustable band.
