Crystal regulator clocks have been very popular for many years. Some of the most famous ones were built by the famous clock making company Seth Thomas. These crystal regulator clocks almost always features mercury filled vials for the pendulum. This was more accurate than a standard pendulum, as when the temperature would change, the pendulums would adjust themselves accordingly. We often think of these clocks as very, very old? but actually these clocks were still being make back in 1905. They are usually decorated with beautiful bronze moldings, and often have engravings or other d?r featured on them. They ranged in sophistication from gaudy, spectacular, and jewel laden to plain, simple, and practical. Needless to say, there was a clock for everyone, no matter what their price range was. These clocks are now very popular collectors' items, often selling for high prices at auctions and sales.
