2. Lever escapement - Wikipedia

   en.wikipedia.org/wiki/Lever_escapement

   The impulse received by the entrance pallet as the tooth moves over the impulse face is transferred by the lever to the balance wheel via the ruby impulse pin on the roller of the balance wheel. The lever moves until it rests against the right banking pin; it is held in this position by the force of the exit tooth against the exit pallet jewel ...

3. Escapement - Wikipedia

   en.wikipedia.org/wiki/Escapement

   Its advantages are (1) it is a "detached" escapement, in which (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 ...

4. Pallet fork - Wikipedia

   en.wikipedia.org/wiki/Pallet_fork

   Pallet fork with jewel pallets (pink) 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 ...

5. Balance wheel - Wikipedia

   en.wikipedia.org/wiki/Balance_wheel

   Early balance wheels were pushed in one direction by the escapement until the verge flag that was in contact with a tooth on the escape wheel slipped past the tip of the tooth ("escaped") and the action of the escapement reversed, pushing the wheel back the other way. In such an "inertial" wheel, the acceleration is proportional to the drive force.

6. Riefler escapement - Wikipedia

   en.wikipedia.org/wiki/Riefler_escapement

   The Riefler escape wheel and pallets are of a special design. There are actually two escape wheels mounted on the same shaft and two surfaces on each of the two pallet pins. The front locking wheel has forward pointing teeth rather like a dead-beat escapement, and catches on the flat surface of the pallet to lock the wheel.

7. Tourbillon - Wikipedia

   en.wikipedia.org/wiki/Tourbillon

   In a tourbillon, the escapement and balance wheel are mounted in a rotating cage, with the goal of eliminating errors of poise in the balance giving a uniform weight. [2] Tourbillons are still included in some modern wristwatches, where the mechanism is usually exposed on the watch's face to showcase it.
