Antique French clock with a mercury pendulum made by Charles Hour

Here is a very elegant antique clock that will look perfect on any mantle shelf, desk or sideboard, and combined with its graceful look, also sounds so beautiful as it strikes the time on the hour and half hour.

Made by the aptly named clock maker, Charles Hour in France in the late 1800's, this clock not only has such an attractive pendulum, but one that was designed not for looks, rather accuracy.

Whereas a standard pendulum can be affected by temperature in that a hot day will expand and subsequently lengthen a pendulum resulting in a longer swing and therefore losing time and the result being not being as accurate, a mercury pendulum overcomes this by having the mercury which is sealed safely in the two vials, giving it nowhere to expand but up. Not only does this result in a very reliable and accurate clock, but aesthetically they are also so visually pleasing to admire.

Fitted with a white enamel dial displaying traditional Roman numerals, the 8-day movement as mentioned earlier strikes so beautifully to tell the hour as well as indicating the half hour and has been completely serviced and comes with our twelve month warranty.

With the white marble complimenting the brass perfectly, sitting atop is that magnificent lion that has such a regal and strong look that accentuates the charm and character of the clock as whole.

Measuring 34cm tall to the top of the base or 40cm to the top of the lion, by 19cm across by 14cm deep, this clock is one that will always be admired no matter what room it is placed in.

Antique French clock with a mercury pendulum made by Charles Hour

 

A brief history on mercury pendulums

Early clocks dating as far back as the 17 and 18th centuries were accurate to around five minutes per week. Although impressive by the standards and materials used to make clocks, a higher degree of accuracy was required especially for scientific purposes and nautical exploration. Around 1720 in England, regulators started being made powered by a weighted and geared mechanism which now meant that they could be accurate to within 10 seconds per month.
Many of the early regulator clocks were fitted with mercury pendulums that were made to compensate for temperature variations that could alter the accuracy of the clock. Put simply, as metal gets warm it expand and can actually lengthen the length of the pendulum, causing the clock to run slower. However, using a mercury pendulum compensates this as the mercury - which is sealed safely in the vial - has nowhere to expand but up.
