Detent escapement for wrist-watches

摘要

The escapement has a blocker, and a plate (4) with an impulse pallet. Two arms (9, 10) of the blocker carry a rest pallet and an activation finger. A spiral spring (12) is mounted on the plate and includes coils winded around a center. Another activation finger drives the former finger when the plate rotates in one direction to activate the blocker and is prevented from driving the finger when rotated in opposite direction.
