Within a few years the Sessions Clock Company was producing clock movements, cases, dials, artwork and castings for their line of mechanical clocks. Between 1903 and 1933 Sessions produced 52 models of mechanical clocks, ranging from Advertisers, large and small clocks with logos of various businesses, to wall, or regulator clocks, and shelf or ...
Elias Ingraham (1805–1885) opened his own shop in Bristol in 1831 as a cabinetmaker and designer of clock cases. [1] While on a voyage to Caracas, Venezuela in the 1840s, Elias designed the four-column Sharp Gothic steeple clock, which was widely copied by other clock makers and sold so extensively around the world that it is believed to have been the best-seller of any distinctively ...
Additionally, he oversaw Harvard's management of its clocks. Willard presented two clocks to Harvard. One was a tall-case clock; the other was a wall-mounted regulator clock that was installed in a room near University Hall. A particular incident relates to Harvard's Great Orrery which was malfunctioning. Many craftsmen had unsuccessfully ...
Benjamin Vulliamy. Benjamin Vulliamy (1747 – 31 December 1811), was a British clockmaker responsible for building the Regulator Clock, which, between 1780 and 1884, was the main timekeeper of the King's Observatory Kew and the official regulator of time in London. [2] In 1773 Vulliamy had received a Royal Appointment as the King's Clockmaker.
The Waltham Watch Company, also known as the American Waltham Watch Co. and the American Watch Co., was a company that produced about 40 million watches, clocks, speedometers, compasses, time delay fuses, and other precision instruments in the United States of America between 1850 and 1957.

A bracket clock is a style of antique portable table clock made in the 17th and 18th centuries. [1] The term originated with small weight-driven pendulum clocks (sometimes called 'true bracket clocks') that had to be mounted on a bracket on the wall to allow room for their hanging weights. [2] When spring-driven clocks were developed, which ...
The spiral balance spring is visible at top. A balance wheel, or balance, is the timekeeping device used in mechanical watches and small clocks, analogous to the pendulum in a pendulum clock. It is a weighted wheel that rotates back and forth, being returned toward its center position by a spiral torsion spring, known as the balance spring or ...
This clock has clear synthetic ruby pallets. (Dial on the right side.) The Riefler escapement is a mechanical escapement for precision pendulum clocks invented and patented [1] by German instrument maker Sigmund Riefler in 1889.
