Swiss anchor escapement for wristwatch, has output pallet whose pulse face has angular length measured from center of escape wheel and in position at which rest tip of tooth of escape wheel is in contact with rest tip of output pallet

摘要

The escapement has an anchor (3) provided with an input pallet (4) and an output pallet (5), where an angular length (Ls) of a pulse face (10) of the output pallet is higher than 7.5 degrees. The angular length is measured from a center (C1) of an escape wheel (1) and in a position at which a rest tip of a tooth (2) of the escape wheel is in contact with a rest tip of the output pallet. An angular length of a pulse face of teeth of the escape wheel is higher than 2 degrees and measured from the center of the escape wheel.
