Normally one finds the highly unusual pin escapement used here in long case or turret clocks. The pin escapement was originally invented by Italian physician and astronomer Galileo Galilei; it is easier to make than a lever escapement and much more robust. The construction has two pallets that usually are of different length and catch and release the pins on the wheel alternately; the wheel is perpendicular to its rotation plane. Galileo’s invention paved the way for a great number of later escapement mechanisms.
