Mechanical watch A mechanical watch is a watch that uses a mechanism to measure the passage of time, as opposed to modern quartz watches which function electronically. It is driven by a spring (called a mainspring) which must be wound periodically. Its force is transmitted through a series of gears to power the balance wheel, a weighted wheel which oscillates back and forth at a constant rate. A device called an escapement releases the watch's wheels to move forward a small amount with each swing of the balance wheel, moving the watch's hands forward at a constant rate. This makes the 'ticking' sound characteristic of all mechanical watches. Mechanical watches evolved in Europe in the 17th century from spring powered clocks, which appeared in the 15th century.

Longcase clock A longcase clock, also tall-case clock, floor clock, or grandfather clock, is a tall, freestanding, weight-driven pendulum clock with the pendulum held inside the tower or waist of the case. Clocks of this style are commonly 1.8–2.4 metres (6–8 feet) tall. The case often features elaborately carved ornamentation on the hood (or bonnet), which surrounds and frames the dial, or clock face. The English clockmaker William Clement is credited with the development of this form in 1670. Until the early 20th century, pendulum clocks were the world's most accurate timekeeping technology, and longcase clocks, due to their superior accuracy, served as time standards for households and businesses. Today they are kept mainly for their decorative and antique value.

History of aviation in Canada The history of aviation in Canada begins with the first manned flight in a balloon at Saint John, New Brunswick in 1840. Development of the aviation industry in Canada was shaped by the interplay of Canadian national ambitions, national and international politics, economics, and technology. Experimental aviation started in Canada with the test flights of Bell's Silver Dart in 1909, following the epochal flight of the Wright Brothers in 1903. The experimental phase gave way to use of aircraft in warfare and many Canadians served in the British Royal Flying Corps and Royal Air Force during the First World War.
