Corydon Clock – The Blog

As http://WatchPart.co.uk puts it: Horology is the formal term for the science of timekeeping. Both clock and watchmaking have seen many significant technological advancements in modern times as they progressed from the early days of the spring powered clock up to IBM’s Linux Wrist Watch project. Most advancements in horology in the modern era have [...]

By Robert Thatcher The craft of clock making is said to have started in Black Forest, Germany. The abundance of both time and woods have fashioned the idea of creating clocks, which was followed after an imported clock from a nearby area. The first clocks that were produced in this region were rather primitive but [...]

If you are planning to repair watches .. first you will need a ‘WATCH REPAIR BENCH’ If a standard watch repair bench is not available, have one made approximately 38 inches high, 22 inches deep, 40 inches long. Each side should contain several drawers for holding tools. Source: Modern Watch and Clock Repairing

NIST Time and Frequency Services Since 1923, NIST radio station WWV has provided round-the-clock shortwave broadcasts of time and frequency signals. WWV’s audio signal is also offered by telephone: dial (303) 499-7111 (not toll-free). A sister station, WWVH, was established in 1948 in Hawaii, and its signal can be heard by dialing (808) 335-4363 in [...]

World Time Scales In the 1840s a railway standard time for all of England, Scotland, and Wales evolved, replacing several “local time” systems. The Royal Observatory in Greenwich began transmitting time telegraphically in 1852 and by 1855 most of Britain used Greenwich time. Greenwich Mean Time (GMT) subsequently evolved as an important and well-recognized time [...]

The “Atomic Age” of Time Standards Scientists had long realized that atoms (and molecules) have resonances; each chemical element and compound absorbs and emits electromagnetic radiation at its own characteristic frequencies. These resonances are inherently stable over time and space. An atom of hydrogen or cesium here today is (so far as we know) exactly [...]

A Revolution in Timekeeping In Europe during most of the Middle Ages (roughly 500 CE to 1500 CE), technological advancement virtually ceased. Sundial styles evolved, but didn’t move far from ancient Egyptian principles. During these times, simple sundials placed above doorways were used to identify midday and four “tides” (important times or periods) of the [...]

Early Clocks Not until somewhat recently (that is, in terms of human history) did people find a need for knowing the time of day. As best we know, 5000 to 6000 years ago great civilizations in the Middle East and North Africa began to make clocks to augment their calendars. With their attendant bureaucracies, formal [...]

Ancient Calendars Celestial bodies — the Sun, Moon, planets, and stars — have provided us a reference for measuring the passage of time throughout our existence. Ancient civilizations relied upon the apparent motion of these bodies through the sky to determine seasons, months, and years. We know little about the details of timekeeping in prehistoric [...]
