The clock measures just over a metre in height (1080mm) and is 305mm wide and 100mm deep. ![]() The ordering process allows you to choose the colours of the wheels, hands and plates, with nine different options to select from so that you can really customize it to your tastes. Carbon fibre pendulum rod with low thermal coefficient of expansion for best timekeepingĮach one is made to order, with average delivery times of 6 – 8 weeks to allow for production and testing.9 precision ball axle bearings and 2 bronze anchor bearings to minimize friction.The technical specifications are also very impressive and read as follows: ![]() Important features such as the dial layout and the repartition of the gear train are taken directly from Grossmann’s explanations resulting in a reliable and accurate clock that is both fascinating and attractive to look at. His latest project is Ingénieur du Temps, a company which creates 3D printed pendulum clocks based on the design criteria and practical solutions for a precision regulator clock set out by Moritz Grossmann, founder of the German Watchmaking School in Glashütte, in an article he wrote in 1878. You can read the full article and see the photos of the watch here. Corson’s name from a previous article we wrote – all the way back in 2011! The moderator of the AHCI and Independent Haute Horlogerie forum at PuristSPro, and a self-taught watch-maker to boot, he had created a very nice, hand-made tourbillon wristwatch as part of the PuristPro 10 th Anniversary celebrations. Long-time readers of MONOCHROME with exceptional memories might recognise Mr. Although MONOCHROME-favourite MB&F is doing their best to change that, with beautiful mechanical desk clocks like the recently introduced Octopod.Īnother man is also trying to change people’s perceptions of the humble clock: Don Corson. Although they’re still extremely precise, more practical and price-friendly options are available, plus people just don’t think about mechanical clocks the way they used to. These days mechanical pendulum clocks are considered largely ornamental. This was solved by the invention of temperature-compensated pendulums, which resulted in the clocks achieving accuracies of a few seconds per week by the mid-18th century. Eventually, clockmakers figured out that the thermal expansion and contraction of the pendulum rod caused by changes in temperature was a source of error. When the weather got warmer, during the summer, for instance, pendulum clocks slowed down. These advancements further improved the accuracy and reliability of pendulum clocks, but another issue soon became apparent. Commonly referred to as the Graham escapement, it is used in most modern pendulum clocks. This was later superseded again by the deadbeat escapement, which was invented in 1675 by Richard Towneley, and later popularized by George Graham and his precision “regulator” clocks. However, Huygens determined that wide swings made the pendulum inaccurate, which led to the invention of the anchor escapement around 1670 that reduced the pendulum’s swing to just 4–6°. However, there were still more improvements to come.Įarly uses of this technology saw pendulums retrofitted to existing verge and foliot clocks, resulting in wide-swinging pendulums due to the verge escapements used in the clock movements. Incredibly, the introduction of pendulums increased the accuracy of clocks significantly, taking the deviation rate from 15 minutes per day down to just 15 seconds per day. In layman’s terms, this means that the pendulum swings back and forth at a precise time interval dependent on its length, and resists swinging at other rates. As the name suggests, the clock uses a swinging weight (a pendulum), which acts a harmonic oscillator. Textbook content produced by OpenStax is licensed under a Creative Commons Attribution License.
