Movement (clockwork) In horology, a movement, also known as a caliber or calibre ( British English ), is the mechanism of a watch or timepiece, as opposed to the case, which encloses and protects the movement, and the face, which displays the time. The term originated with mechanical timepieces, whose clockwork movements are made of many moving ...
Tourbillon. In horology, a tourbillon ( / tʊərˈbɪljən /; French: [tuʁbijɔ̃] "whirlwind") is an addition to the mechanics of a watch escapement to increase accuracy. Conceived by the British watchmaker and inventor John Arnold, it was developed by his friend the Swiss-French watchmaker Abraham-Louis Breguet and patented by Breguet on 26 ...
The hand-winding movement of a Russian watch. A mechanical watch is a watch that uses a clockwork mechanism to measure the passage of time, as opposed to quartz watches which function using the vibration modes of a piezoelectric quartz tuning fork, or radio watches, which are quartz watches synchronized to an atomic clock via radio waves.
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 ...
Miyota produces various 'standard' and 'premium' grade mechanical movements for automatic wristwatches.. The Miyota 8215 is an entry level [[hack watch-latest versions|non-hacking-earlier versions ] twenty-one jewel three-hand with date automatic wristwatch movement with a uni-directional winding system (left rotation) with an accuracy of -20 to +40 seconds per day, and a power reserve of over ...
The pallet fork is above the balance wheel in this watch movement. The pallet fork is a component of the lever escapement of a mechanical watch. [ 1] The pallet fork and the lever form one component that sits between the escape wheel and the balance wheel. Its purpose is to lock the escape wheel, and release it one tooth at a time at each swing ...
Fusee (horology) A fusee (from the French fusée, wire wound around a spindle) is a cone -shaped pulley with a helical groove around it, wound with a cord or chain attached to the mainspring barrel of antique mechanical watches and clocks. It was used from the 15th century to the early 20th century to improve timekeeping by equalizing the ...
Complication (horology) In horology, a complication is any feature of a timepiece beyond the display of hours, minutes and seconds. A timepiece indicating only hours, minutes and seconds is known as a simple movement. Common complications include date or day-of-the-week indicators, alarms, chronographs (stopwatches), and automatic winding ...
