Its advantages are (1) it is a "detached" escapement; unlike the cylinder or duplex escapements the balance wheel is only in contact with the lever during the short impulse period when it swings through its centre position and swings freely the rest of its cycle, increasing accuracy, and (2) it is a self-starting escapement, so if the watch is ...
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.
The escapement was commercialized in 1999 by Omega SA when it introduced the first mass-produced watch incorporating the technology. [11] It is the only escapement other than the Swiss lever escapement that is produced on an industrial scale. When it first came to the market as the Caliber 2500, it had an oscillation rate of 28,800 beats per ...
The mechanism, which was first unveiled in 1976 (see watch 10 below), the "Atwood") and known as the Daniels independent double wheeled escapement a further version which was patented in 1980, was later called the co-axial escapement [14] and the first named Daniels co-axial escapement watch was watch 17 below (the "Martin").

A typical watch lever escapement beats at 18,000 or more beats per hour. Each beat gives the balance wheel an impulse, so there are two impulses per cycle. Despite being locked at rest most of the time, the escape wheel rotates typically at an average of 10 rpm or more. The origin of the "tick tock" sound is caused by this escapement mechanism.

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 hairspring.
