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.
Each specific watch movement is called a caliber. [3] The movement parts are separated into two main categories: those belonging to the ébauches and those belonging to the assortments. [2] In watch movements the wheels and other moving parts are mounted between two plates, which are held a small distance apart with pillars to make a rigid ...

Tourbillon movement (high resolution)In horology, a tourbillion (/ t ʊər ˈ b ɪ l j ən /) or tourbillon (/ t ʊər b ɪ ˈ j ɒ n /; French: [tuʁbijɔ̃] "whirlwind") is an addition to the mechanics of a watch escapement to increase accuracy.
It is also possible for quartz clocks and watches to have their quartz crystal oscillate at a higher frequency than 32 768 (= 2 15) Hz (high frequency quartz movements [4]) and/or generate digital pulses more than once per second, to drive a stepping motor powered second hand at a higher power of 2 than once every second, [5] but the electric ...
The power reserve indicator is one of the most useful features of a mechanical watch besides the actual time display. A mechanical watch is operated by either automatic or manual winding. In order to run at a regular rate a mechanical timepiece needs to have at least 30 per cent of its mainspring wound.
Amfibia (often spelled "Amphibia") is a Russian dive watch model. It uses a mechanical watch movement available in both manual and automatic winding forms. The Amfibia was developed at the Vostok watch factory in 1967. [1] It later gained worldwide popularity due to its reliable reputation and low cost. [1]
Clockwork of mechanical Prim wrist watch. Clockwork refers to the inner workings of either mechanical devices called clocks and watches (where it is also called the movement) or other mechanisms that work similarly, using a series of gears driven by a spring or weight. [1] [2] [3]
