Learn about antique grandfather clocks and view detailed dial information and photographs by obtaining reference books on the subject. Examples include “Restoring Grandfather Clocks,” by Eric Smith and Brian Smith and “Grandfather Clocks and their Cases,” by Brian Loomes.
Open the top case of the grandfather clock and examine the dial closely. The material used should look and feel like paper, not engraved metal or porcelain.
Tap the dial to feel the surface underneath. Most antique grandfather clock paper dials were placed on top of an iron or wood base, providing a sturdy surface for the paper.
Look for a lacquered effect on the paper dial, as some antique clocks had paper dials with a lacquer on top to provide sheen and protect the paper from wear.
