Quick Summary

The club-tooth escapement is a specific type of lever escapement used in watchmaking. This mechanism is crucial for controlling the release of energy from the watch's power source to its timekeeping components. The club-tooth design, characterized by its club-shaped teeth, was developed to help retain oil within the escapement, contributing to more consistent performance. This innovation was an improvement on earlier lever escapements and became widely adopted in the early 20th century for its reliability in maintaining accurate time.123
