1, tourbillon: 1795 invented clock speed regulating device.
2. Coaxial escapement: an escapement device invented in 1974.
Second, the inventors are different.
1, tourbillon: tourbillon is a kind of clock speed regulating device invented by Swiss master Louis Breguet.
2. Coaxial escapement: It is an escapement device invented by British watchmaker George Daniels.
Third, the characteristics are different.
1, tourbillon: tourbillon's idea is to put the escapement of the clock movement in a carriage and let the frame rotate 360 degrees regularly around the axis, that is, the axis of the balance wheel. In this way, the original escapement mechanism is fixed, so when the static position of the watch changes, the escapement mechanism remains unchanged, resulting in different forces on the escapement parts, resulting in errors; When the escapement mechanism rotates continuously for 360 degrees, the azimuth errors of the parts will be integrated and offset each other, thus minimizing the errors.
2. Coaxial escapement: Coaxial escapement is improved on the basis of lever escapement, which greatly reduces the energy loss. This invention is considered as a breakthrough in clock technology after the lever escapement mechanism. The coaxial escapement mechanism includes three layers of coaxial escapement wheels, which can separate the locking function from the pulse, thus eliminating the sliding resistance of the lever escapement mechanism and eliminating the need to add lubricating oil between pawls.
